This paper presents a new local facial feature descriptor, Local Gray Code Pattern (LGCP), for facial expression recognition in contrast to widely adopted Local Binary pattern. Local Gray Code Pattern (LGCP) characterizes both the texture and contrast information of facial components. The LGCP descriptor is obtained using local gray color intensity differences from a local 3x3 pixels area weighted by their corresponding TF (term frequency). I have used extended Cohn-Kanade expression (CK+) dataset and Japanese Female Facial Expression (JAFFE) dataset with a Multiclass Support Vector Machine (LIBSVM) to evaluate proposed method. The proposed method is performed on six and seven basic expression classes in both person dependent and independent environment. According to extensive experimental results with prototypic expressions on static images, proposed method has achieved the highest recognition rate, as compared to other existing appearance-based feature descriptors LPQ, LBP, LBPU2, LBPRI, and LBPRIU2.

Abstract
LDN characterizes both the texture and contrast information of facial components in a compact way, producing a more discriminative code than other available methods. An LDN code is obtained by computing the edge response values in 8 directions at each pixel with the aid of a compass mask. Image analysis and understanding has recently received significant attention, especially during the past several years. At least two reasons can be accounted for this trend: the first is the wide range of commercial and law enforcement applications, and the second is the availability of feasible technologies after nearly 30 years of research. In this paper we propose a novel local feature descriptor, called Local Directional Number Pattern (LDN), for face analysis, i.e., face and expression recognition. LDN characterizes both the texture and contrast information of facial components in a compact way, producing a more discriminative code than other available methods.
Pose and Illumination in Face Recognition Using Enhanced Gabor LBP & PCA IJMER
This paper presents the face recognition based on Enhanced GABOR LBP and PCA. Some
of the challenges in face recognition are occlusion, pose and illumination .In this paper, we are more
focused on varying pose and illumination. We divided this algorithm into five stages. First stage finds
the fiducial points on face using Gabor filter bank as this filter is well known for illumination
compensation. Second stage applies the morphological techniques for reduce useless fiducial points.
Third stage applies the LBP on reduced fiducial points with neighborhood pixel for improving the pose
variation. Forth stage uses PCA to detect the best variance points which are necessary to characterize
the training images. The last recognition stage includes finding the Euclidean norm of the feature
weight vectors with the test weight vector. In this project, we used 20 images of 20 different persons
from ORL database for training. For testing, we used images with varying illumination, pose and
occluded images of the same training

HVDLP : HORIZONTAL VERTICAL DIAGONAL LOCAL PATTERN BASED FACE RECOGNITION sipij
Face image is an efficient biometric trait to recognize human beings without expecting any co-operation from a person. In this paper, we propose HVDLP: Horizontal Vertical Diagonal Local Pattern based face recognition using Discrete Wavelet Transform (DWT) and Local Binary Pattern (LBP). The face images of different sizes are converted into uniform size of 108×990and color images are converted to gray scale images in pre-processing. The Discrete Wavelet Transform (DWT) is applied on pre-processed images and LL band is obtained with the size of 54×45. The Novel concept of HVDLP is introduced in the proposed method to enhance the performance. The HVDLP is applied on 9×9 sub matrix of LL band to consider HVDLP coefficients. The local Binary Pattern (LBP) is applied on HVDLP of LL band. The final features are generated by using Guided filters on HVDLP and LBP matrices. The Euclidean Distance (ED) is used to compare final features of face database and test images to compute the performance parameters.

50Combining Color Spaces for Human Skin Detection in Color Images using Skin ...idescitation
Skin detection remains a challenging task over
several decades in spite of many techniques evolved. It is the
elementary step of most of the computer vision applications
like face recognition, human computer interaction, etc. It
depends on the suitability of color space chosen, skin modeling
and classification of skin and non-skin pixels under varying
illumination conditions. This paper presents a symbolic
interpretation on the performance of the color spaces using
piecewise linear decision boundary classifier in color images
to find the winning color space (s). The whole task is divided
into three processes: analysis of color spaces individually;
analysis of the combination of two color spaces; and finally
making a comparative analysis among the results obtained by
the above two processes. For performing the fair evaluation,
the whole experiment is tested over commonly used databases.
Based on the success rate, false positive and false negative of
each color spaces, the winner(s) has been chosen among single
and the combination of color spaces.
An improved double coding local binary pattern algorithm for face recognitioneSAT Journals
Abstract A human face conveys a lot of information about the identity and emotional state of the person. So now a day’s face recognition has become an interesting and challenging problem. Face recognition plays a vital role in many applications such as authenticating a person, system security, verification and identification for law enforcement and personal identification among others. So our research work mainly consists of three parts, namely face representation, feature extraction and classification. The first part, Face representation represents how to model a face and check which algorithms can be used for detection and recognition purpose. In the second phase i.e. feature extraction phase we compute the unique features of the face image. In the classification phase the computed DLBP face image is compared with the images from the database. In our research work, we use Double Coding Local Binary Patterns to evaluate face recognition which concentrate over both the shape and texture information to represent face images for person independent face recognition. The face area is firstly cut into small regions from which Local Binary Patterns (LBP), then we compute histograms to generate LBP image then we compute single oriented mean image from which we again compute histogram values small regions and at last concatenated into a single feature vectors and generate D-LBP image. This feature are used for the representation of the face and to measure similarities between images. Keywords: local binary pattern (LBP), double coding local binary pattern (D-LBP), features extraction, classification, pattern recognition, histogram, feature vector.
Face Recognition based on STWT and DTCWT using two dimensional Q-shift Filters IJERA Editor
The Biometrics is used to recognize a person effectively compared to traditional methods of identification. In this paper, we propose a Face recognition based on Single Tree Wavelet Transform (STWT) and Dual Tree Complex Wavelet transform (DTCWT). The Face Images are preprocessed to enhance quality of the image and resize. DTCWT and STWT are applied on face images to extract features. The Euclidian distance is used to compare features of database image with test face images to compute performance parameters. The performance of STWT is compared with DTCWT. It is observed that the DTCWT gives better results compared to STWT technique.
Improved Face Recognition across Poses using Fusion of Probabilistic Latent V...TELKOMNIKA JOURNAL
Uncontrolled environments have often required face recognition systems to identify faces
appearing in poses that are different from those of the enrolled samples. To address this problem,
probabilistic latent variable models have been used to perform face recognition across poses. Although
these models have demonstrated outstanding performance, it is not clear whether richer parameters
always lead to performance improvement. This work investigates this issue by comparing performance of
three probabilistic latent variable models, namely PLDA, TFA, and TPLDA, as well as the fusion of these
classifiers on collections of video data. Experiments on the VidTIMIT+UMIST and the FERET datasets
have shown that fusion of multiple classifiers improves face recognition across poses, given that the
individual classifiers have similar performance. This proves that different probabilistic latent variable
models learn statistical properties of the data that are complementary (not redundant). Furthermore, fusion
across multiple images has also been shown to produce better perfomance than recogition using single
still image.
Advanced Hybrid Color Space Normalization for Human Face Extraction and Detec...ijsrd.com
This paper presents a new color space normalization (CSN) technique for enhancing the discriminating power of color space along with the principal component analysis (PCA) for the face recognition process. The common RGB technique is not suitable for the characterizing of the skin color due to the presence of luminance factor. In the YCbCr color space, the luminance information is contained in Y component, and the chrominance information is in Cb and Cr. Therefore, the luminance information can be easily de-embedded. Different color spaces have different discriminating power, in this paper, eye can be perfectly detected by using YcbCr color space and the mouth regions can be perfectly detected by using the YIQ color space. Then PCA is used to express the large 1-D vector of pixels constructed from 2-D facial image into the compact principal components of the feature space. Each face image may be represented as a weighted sum (feature vector) of the eigenfaces, which are stored in a 1D array. PCA allows us to compute a linear transformation that maps data from a high dimensional space to a lower dimensional space. It covers standard deviation, covariance, eigenvectors and eigenvalues. Face recognition is obtained by PCA without much loss of information. Experiments using different databases by varying the facial expressions (open/closed eyes, smiling/not smiling) show that the proposed method by combining color space discrimination and PCA can improve face recognition to a great extend.
DEVELOPMENT OF AN ANDROID APPLICATION FOR OBJECT DETECTION BASED ON COLOR, SH...ijma
Object detection and recognition is an important task in many computer vision applications. In this paper
an Android application was developed using Eclipse IDE and OpenCV3 Library. This application is able to
detect objects in an image that is loaded from the mobile gallery, based on its color, shape, or local
features. The image is processed in the HSV color domain for better color detection. Circular shapes are
detected using Circular Hough Transform and other shapes are detected using Douglas-Peucker
algorithm. BRISK (binary robust invariant scalable keypoints) local features were applied in the developed
Android application for matching an object image in another scene image. The steps of the proposed
detection algorithms are described, and the interfaces of the application are illustrated. The application is
ported and tested on Galaxy S3, S6, and Note1 Smartphones. Based on the experimental results, the
application is capable of detecting eleven different colors, detecting two dimensional geometrical shapes
including circles, rectangles, triangles, and squares, and correctly match local features of object and scene
images for different conditions. The application could be used as a standalone application, or as a part of
another application such as Robot systems, traffic systems, e-learning applications, information retrieval
and many others.
In this paper, an attempt has been made to extract texture
features from facial images using an improved method of
Illumination Invariant Feature Descriptor. The proposed local
ternary Pattern based feature extractor viz., Steady Illumination
Local Ternary Pattern (SIcLTP) has been used to extract texture
features from Indian face database. The similarity matching
between two extracted feature sets has been obtained using Zero
Mean Sum of Squared Differences (ZSSD). The RGB facial images
are first converted into the YIQ colour space to reduce the
redundancy of the RGB images. The result obtained has been
analysed using Receiver Operating Characteristic curve, and is
found to be promising. Finally the results are validated with
standard local binary pattern (LBP) extractor.

Illumination Invariant Face Recognition System using Local Directional Patter...Editor IJCATR
In this paper, we propose an illumination-robust face recognition system using local directional pattern images. Usually,
local pattern descriptors including local binary pattern and local directional pattern have been used in the field of the face recognition
and facial expression recognition, since local pattern descriptors have important properties to be robust against the illumination
changes and computational simplicity. Thus, this paper represents the face recognition approach that employs the local directional
pattern descriptor and two-dimensional principal analysis algorithms to achieve enhanced recognition accuracy. In particular, we
propose a novel methodology that utilizes the transformed image obtained from local directional pattern descriptor as the direct input
image of two-dimensional principal analysis algorithms, unlike that most of previous works employed the local pattern descriptors to
acquire the histogram features. The performance evaluation of proposed system was performed using well-known approaches such as

Multi-Directional Multi-Level Dual-Cross Patterns for Robust Face RecognitionPeachy Essay
To perform unconstrained face recognition robust to variations in illumination, pose and expression, this paper presents a
new scheme to extract “Multi-Directional Multi-Level Dual-Cross Patterns” (MDML-DCPs) from face images. Specifically, the MDMLDCPs scheme exploits the first derivative of Gaussian operator to reduce the impact of differences in illumination and then computes the DCP feature at both the holistic and component levels. DCP is a novel face image descriptor inspired by the unique textural structure of human faces. It is computationally efficient and only doubles the cost of computing local binary patterns, yet is extremely robust to pose and expression variations. MDML-DCPs comprehensively yet efficiently encodes the invariant characteristics of a face image from multiple levels into patterns that are highly discriminative of inter-personal differences but robust to intra-personal variations.
Experimental results on the FERET, CAS-PERL-R1, FRGC 2.0, and LFW databases indicate that DCP outperforms the state-of-the-art local descriptors (e.g. LBP, LTP, LPQ, POEM, tLBP, and LGXP) for both face identification and face verification tasks. More impressively, the best performance is achieved on the challenging LFW and FRGC 2.0 databases by deploying MDML-DCPs in a simple recognition scheme.
Facial recognition using modified local binary pattern and random forestijaia
This paper presents an efficient algorithm for face recognition using the local binary pattern (LBP) and
random forest (RF). The novelty of this research effort is that a modified local binary pattern (MLBP),
which combines both the sign and magnitude features for the improvement of facial texture classification
performance, is applied. Furthermore, RF is used to select the most important features from the extracted
feature sequence. The performance of the proposed scheme is validated using a complex dataset, namely

MONOGENIC SCALE SPACE BASED REGION COVARIANCE MATRIX DESCRIPTOR FOR FACE RECO...cscpconf
In this paper, we have presented a new face recognition algorithm based on region covariance
matrix (RCM) descriptor computed in monogenic scale space. In the proposed model, energy
information obtained using monogenic filter is used to represent a pixel at different scales to
form region covariance matrix descriptor for each face image during training phase. An eigenvalue
based distance measure is used to compute the similarity between face images. Extensive
experimentation on AT&T and YALE face database has been conducted to reveal the
performance of the monogenic scale space based region covariance matrix method and
comparative analysis is made with the basic RCM method and Gabor based region covariance matrix method to exhibit the superiority of the proposed technique.

Statistical Models for Face Recognition System With Different Distance MeasuresCSCJournals
Face recognition is one of the challenging applications of image processing. Robust face recognition algorithm should posses the ability to recognize identity despite many variations in pose, lighting and appearance. Principle Component Analysis (PCA) method has a wide application in the field of image processing for dimension reduction of the data. But these algorithms have certain limitations like poor discriminatory power and ability to handle large computational load. This paper proposes a face recognition techniques based on PCA with Gabor wavelets in the preprocessing stage and statistical modeling methods like LDA and ICA for feature extraction. The classification for the proposed system is done using various distance measure methods like Euclidean Distance(ED), Cosine Distance (CD), Mahalanobis Distance (MHD) methods and the recognition rate were compared for different distance measures. The proposed method has been successfully tested on ORL face data base with 400 frontal images corresponding to 40 different subjects which are acquired under variable illumination and facial expressions. It is observed from the results that use of PCA with Gabor filters and features extracted through ICA method gives a recognition rate of about 98% when classified using Mahalanobis distance classifier. This recognition rate stands better than the conventional PCA and PCA + LDA methods employing other and classifier techniques.
Selective local binary pattern with convolutional neural network for facial ...IJECEIAES
Variation in images in terms of head pose and illumination is a challenge in facial expression recognition. This research presents a hybrid approach that combines the conventional and deep learning, to improve facial expression recognition performance and aims to solve the challenge. We propose a selective local binary pattern (SLBP) method to obtain a more stable image representation fed to the learning process in convolutional neural network (CNN). In the preprocessing stage, we use adaptive gamma transformation to reduce illumination variability. The proposed SLBP selects the discriminant features in facial images with head pose variation using the median-based standard deviation of local binary pattern images. We experimented on the Karolinska directed emotional faces (KDEF) dataset containing thousands of images with variations in head pose and illumination and Japanese female facial expression (JAFFE) dataset containing seven facial expressions of Japanese females’ frontal faces. The experiments show that the proposed method is superior compared to the other related approaches with an accuracy of 92.21% on KDEF dataset and 94.28% on JAFFE dataset.
Effectual Face Recognition System for Uncontrolled IlluminationIIRindia
Facial recognition systems are biometric methods used to pinpoint the identities of faces present in various digital formats by comparing them to facial databases. The variation in illuminating conditions is a huge hindrance for efficient operation of facial verification systems. The effects of change in ambient lighting conditions and formation of shadows can be nullified by an effortless pre-processing system. This paper presents an effectual Facial Recognition System which consists of three stages: the illumination insensitive preprocessing method, Feature Extraction and Score Fusion. In the preprocessing stage, the light-sensitive images are converted to light-insensitive images so that uncontrolled lighting will no more be a liability for any kind of identification. In the feature extraction stage, hybrid Fourier classifiers are used to obtain transforms which are projected into subspaces using PCLDA Theory. And the output is passed onto the Score Fusion stage where the discriminating powers of the classifiers are unified by using LLR and knowing the ground truth optimizations. This proposal has passed the Face Recognition Grand Challenge (FRGC) Version-2 Experiment, Extended Yale B and FERET datasets.
COMPRESSION BASED FACE RECOGNITION USING TRANSFORM DOMAIN FEATURES FUSED AT M...sipij
The physiological biometric trait face images are used to identify a person effectively. In this paper, we
propose compression based face recognition using transform domain features fused at matching level. The
2D images are converted into 1-D vectors using mean to compress number of pixels. The Fast Fourier
Transform (FFT) and Discrete Wavelet Transform (DWT) are used to extract features. The low and high
frequency coefficients of DWT are concatenated to obtained final DWT features. The performance
parameters are computed by comparing database and test image features of FFT and DWT using Euclidian
Distance (ED). The performance parameters of FFT and DWT are fused at matching level to obtain better
results. It is observed that the performance of proposed method is better than the existing methods.

Local directional number pattern for face analysis face and expression recognition
1. Local Directional Number Pattern for Face Analysis: Face and
Expression Recognition
ABSTRACT:
This paper proposes a novel local feature descriptor, local directional number pattern (LDN),
for face analysis, i.e., face and expression recognition. LDN encodes the directional information
of the face’s textures (i.e., the texture’s structure) in a compact way, producing a more
discriminative code than current methods. We compute the structure of each micro-pattern with
the aid of a compass mask that extracts directional information, and we encode such
information using the prominent direction indices (directional numbers) and sign—which
allows us to distinguish among similar structural patterns that have different intensity
transitions. We divide the face into several regions, and extract the distribution of the LDN
features from them. Then, we concatenate these features into a feature vector, and we use it as a
face descriptor. We perform several experiments in which our descriptor performs consistently
under illumination, noise, expression, and time lapse variations. Moreover, we test our
descriptor with different masks to analyze its performance in different face analysis tasks

2. In the literature, there are many methods for the holistic class, such as, Eigenfaces and
Fisherfaces, which are built on Principal Component Analysis (PCA); the more recent 2D PCA,
and Linear Discriminant Analysis are also examples of holistic methods. Although these
methods have been studied widely, local descriptors have gained attention because of their
robustness to illumination and pose variations. Heiseleet al.showed the validity of the
component-based methods, and how they outperform holistic methods. The local-feature
methods compute the descriptor from parts of the face, and then gather the information into one
descriptor. Among these methods are Local Features Analysis, Gabor features, Elastic Bunch
Graph Matching, and Local Binary Pattern (LBP). The last one is an extension of the LBP
feature that was originally designed for texture description, applied to face recognition. LBP
achieved better performance than previous methods, thus it gained popularity, and was studied
extensively. Newer methods tried to overcome the shortcomings of LBP, like Local Ternary
Pattern (LTP), and Local Directional Pattern (LDiP). The last method encodes the directional
information in the neighborhood, instead of the intensity. Also, Zhanget al. explored the use of
higher order local derivatives (LDeP) to produce better results than LBP. Both methods use
other information, instead of intensity, to overcome noise and illumination variation problems.
However, these methods still suffer in non-monotonic illumination variation, random noise, and
changes in pose, age, and expression conditions. Although some methods, like Gradientfaces,
have a high discrimination power under illumination variation, they still have low recognition
capabilities for expression and age variation conditions. However, some methods explored
different features, such as, infrared, near infrared, and phase information, to overcome the
illumination problem while maintaining the performance under difficult conditions.
DISADVANTAGES OF EXISTING SYSTEM:
Both methods use other information, instead of intensity, to overcome noise and
illumination variation problems.
However, these methods still suffer in non-monotonic illumination variation, random
noise, and changes in pose, age, and expression conditions.
3. Although some methods, like Gradientfaces, have a high discrimination power under
illumination variation, they still have low recognition capabilities for expression and age
variation conditions.
PROPOSED SYSTEM:
In this paper, we propose a face descriptor, Local Directional Number Pattern (LDN), for robust
face recognition that encodes the structural information and the intensity variations of the face’s
texture. LDN encodes the structure of a local neighborhood by analyzing its directional
information. Consequently, we compute the edge responses in the neighborhood, in eight
different directions with a compass mask. Then, from all the directions, we choose the top
positive and negative directions to produce a meaningful descriptor for different textures with
similar structural patterns. This approach allows us to distinguish intensity changes (e.g., from
bright to dark and vice versa) in the texture. Furthermore, our descriptor uses the information of
the entire neighborhood, instead of using sparse points for its computation like LBP. Hence, our
approach conveys more information into the code, yet it is more compact—as it is six bit long.
Moreover, we experiment with different masks and resolutions of the mask to acquire
characteristics that may be neglected by just one, and combine them to extend the encoded
information. We found that the inclusion of multiple encoding levels produces an improvement
in the detection process.
ADVANTAGES OF PROPOSED SYSTEM:
1) The coding scheme is based on directional numbers, instead of bit strings, which encodes
the information of the neighborhood in a more efficient way
2) The implicit use of sign information, in comparison with previous directional and
derivative methods we encode more information in less space, and, at the same time,
discriminate more textures; and
3) The use of gradient information makes the method robust against illumination changes
and noise.
