This document discusses face detection techniques. It defines face detection as identifying regions in images that contain faces. Face detection is important for applications like security, video retrieval, and human-computer interfaces. The document categorizes face detection methods as either image-based, which use training to compare faces to non-faces, or knowledge-based, which detect facial features like skin, eyes and mouths. It provides examples of techniques within each category and notes that image-based methods are more complex while knowledge-based techniques are usually faster. The document concludes by outlining some open issues in face detection.

With so much of our lives computerized, it is vitally important that machines and humans can understand one another and pass information back and forth. Mostly computers have things their way we have to & talk to them through relatively crude devices such as keyboards and mice so they can figure out what we want them to do. However, when it comes to processing more human kinds of information, like an old-fashioned printed book or a letter scribbled with a fountain pen, computers have to work much harder. That is where optical character recognition (OCR) comes in. Here we process the image, where we apply various pre-processing techniques like desk wing, binarization etc. and algorithms like Tesseract to recognize the characters and give us the final document.

HUMAN FACE RECOGNITION USING IMAGE PROCESSING PCA AND NEURAL NETWORKijiert bestjournal
Security and authentication of a person is a vital part of any business. There are many techniques use d for this purpose. One of technique is human face recognition . Human Face recognition is an effective means of authenticating a person. The benefit of this approa ch is that,it enables us to detect changes in the face pattern of an individual to substantial extent. The recognition s ystem can tolerate local variations in the face exp ression of an individual. Hence Human face recognition can be use d as a key factor in crime detection mainly to iden tify criminals. There are several approaches to Human fa ce recognition of which Image Processing Principal Component Analysis (PCA) and Neural Networks have been includ ed in our project. The system consists of a databas e of a set of facial patterns for each individual. The charact eristic features called �eigenfaces� are extracted from the stored images using which the system is trained for subseq uent recognition of new images.
Face Recognition Based Attendance System with Auto Alert to Guardian using Ca...ijtsrd
Now a days the wise attending management system victimization face detection techniques. Daily attending marking could also be a typical and vital activity in colleges and colleges for checking the performance of students. Manual attending maintaining is tough methodology, significantly for large cluster of students. Some machine driven systems developed to x beat these difficulties, have drawbacks like worth, faux attending, accuracy, meddlesomeness. To beat these drawbacks, there is need of good and automatic attending system. We've a bent to unit implementing attending system victimization face recognition. Since face is exclusive identity of person, the problem of pretend attending and proxies could also be resolved. The system uses native binary pattern face recognition technique because it is fast, straightforward and has larger success rate. Also, its pro vision to have an effect on intensity of sunshine draw back and head produce draw back that produces it effective. This wise system could also be degree effective because of maintain the degree will less squat recognition system is planned supported appearance based choices that concentrate on the shortened squatter image rather than native countenance. The remainder step in squatter recognition system is squatter detection Viola Jones squatter detection methodology that capable of method photos terribly whereas achieving higher detection rates is utilized. The complete squatter recognition methodology could also be divided into a pair of parts squatter detection and squatter identification. For face detection, Viola Jones face detection methodology has been used out of the many face detection ways that. Once face detection, face is cropped from the actual image to urge obviate the background. Chemist faces and shear faces ways that are used for face identification.

AN IMPROVED TECHNIQUE FOR HUMAN FACE RECOGNITION USING IMAGE PROCESSINGijiert bestjournal
Face recognition is a computer application technique for automatically identifying or
verifying a person from a digital image or a video frame source. To do this is by comparing
selected facial features from the digital image and a face dataset. It is basically used in
security systems and can be compared to other biometrics such as fingerprint recognition or
eye, iris recognition systems. The main limitation of the current face recognition system is
that they only detect straight faces looking at the camera. Separate versions of the system
could be trained for each head orientation, and the results can be combined using arbitration
methods similar to those presented here. In earlier work, the face position must be centerlight
position; any lighting effect will affect the system. Similarly the eyes of person must be
open and without glass.
Humans often use faces to recognize individuals, and advancements in computing capability over the past few decades now enable similar recognitions automatically. Early facial recognition algorithms used simple geometric models, but the recognition process has now matured into a science of sophisticated mathematical representations and matching processes. Major advancements and initiatives in the past 10 to 15 years have propelled facial recognition technology into the spotlight. Facial recognition can be used for both verification and identification.
Now days, the task of face recognition is widely used application of image analysis as well as pattern recognition. In biometric area of the research, automatically face & face expression recognition attracts researcher’s interest. For classifying facial expressions into different categories, it is necessary to extract important facial features which contribute in identifying proper and particular expressions. Recognition and classification of human facial expression by computer is an important issue to develop automatic facial expression recognition system in vision community. In this paper the facial expression recognition system is proposed.

4. What is Face Detection ?
Face detection is to identify and detect all image
regions in an image which contain a face regardless
of its three-dimensional position, orientation, and
lighting conditions, and if there is a face present in
the image, return its location and extent of the face.
The process is complex and challenging because it
needs to detect faces which are non-rigid and have a
high degree of variability in size, shape, color, and
texture.

mixed with face recognition, human computer
interface, face recognition and image database
management.
2) Modern digital cameras automatically focus on the
faces when those are detected. Some of the
cameras can also detect facial expressions such as
a smile and then automatically captures the
photograph without the actual need of a

3) Face detection is getting immensely
important for marketers as well. A webcam can
be integrated into a television which can detect
the face of any person who walks by. Then the
system can calculate the race, gender, and an
approximate age of the person by analyzing the
person’s facial features. Once the information is
collected, a series of advertisements can be

Knowledge based techniques use information about
facial features, skin color or template matching.
Facial features include eyes, mouth, nose or other
facial features to detect the human faces. Skin color
is different from other colors, and its characteristics
do not change with respect to changes in pose and
occlusion. Because of this, skin color detection is
often the first step of a knowledge based face
detection algorithm.

1. There can be insufficient luminance in the image i.e. the image might be too
dark. Skin color cannot be detected in these cases and hence most of the
algorithms fail. And there is not enough difference between the pixels
belonging to the facial region of the image and those belonging to non facial
region of the image.
2. Cases where the face is entirely covered with beard and the eyes are hidden
behind sunglasses have not yet been addressed. In that case neither the skin
detection will work nor will the facial feature detection work.
3. If the background is of skin color and there is a face in front of that where
there is hardly any difference between the skin color of the face and the
background there are no algorithm which can detect it. Though the facial
features might be detected but the exact face will be almost impossible to
detect.
4. Also if the face is rotated to such an extent that the nose cannot be spotted
anymore, then also it would be impossible to identify the facial region with
the existing systems.
