This document summarizes a research paper about developing a computer program that can take a 2D photograph as input, analyze it to determine the objects and their 3D structure, and output a 3D representation that can be viewed from any angle. The program makes assumptions about the objects, such as they are constructed from transformations of known 3D models and are supported by other visible objects or a ground plane. It develops processes for 2D to 3D construction and 3D to 2D display that can handle most arrangements of objects with planar surfaces.
A PREDICTION METHOD OF GESTURE TRAJECTORY BASED ON LEAST SQUARES FITTING MODELVLSICS Design
Implicit interaction based on context information is widely used and studied in the virtual scene. In context
based human computer interaction, the meaning of action A is well defined. For instance, the right wave is
defined turning paper or PPT in context B, And it mean volume up in context C. However, we cannot use
the context information when we select the object to be manipulated. In view of this situation, this paper
proposes using the least squares fitting curve beam to predict the user's trajectory, so as to determine what
object the user’s wants to operate. At the same time, the fitting effects of the three curves were compared,
and the curve which is more accord with the hand movement trajectory is obtained. In addition, using the
bounding box size control the Z variable to move in an appropriate location. Experimental results show
that the proposed in this paper based on bounding box size to control the Z variables get a good effect; by
fitting the trajectory of a human hand, to predict the object that the subjects would like to operate. The
correct rate is 91%.

The Extraction of Spatial Features from remotely sensed data and the use of this information as input into further decision making systems such as geographical information systems (GIS) has received considerable attention over the few decades. The successful use of GIS as a decision support tool can only be achieved, if it becomes possible to attach a quality label to the output of each spatial analysis operation. Thus the accuracy of Spatial Feature Extraction gained more attention as geographic features can hardly formulated in a certain pattern due to intra-class variation and inter-class similarity. Besides these Spatial Feature Extraction further include positional uncertainty, attribute uncertainty, topological uncertainty, inaccuracy, imprecision/inexactitude, inconsistency, incompleteness, repetition, vagueness, noisy, omittance, misinterpretation, misclassification, abnormalities and knowledge uncertainty. To control and reduce uncertainty in an acceptable degree, a Probabilistic shape model is described for Extracting Spatial Features from multi-spectral image. The advantages of this, as opposed to the conventional approaches, are greater accuracy and efficiency, and the results are in a more desirable form for most purposes.

Face Recognition has develop one of the most effective presentations of image analysis. This area of research is important not only for the applications in human computer interaction, biometric and security but also in other pattern classification problem. To improve face recognition in this system, two methods are used PCA Principal component analysis and SOM Self organizing feature Map .PCA is a subspace projection method is used compress the input face image. SOM method is used to classify DCT based feature vectors into groups to identify if the subject in the input image is "present" or "not present" in the image database. The aim of this system is that input image has to compare with stored images in the database using PCA and SOM method. An image database of 100 face images is evaluated containing 10 subjects and each subject having 10 images with different facial expression. This system is evaluated by measuring the accuracy of recognition rate. This system has been implemented by MATLAB programming.

A Survey on Approaches for Object Trackingjournal ijrtem
ABSTRACT : Object detection and tracking has been a widely studied research problem in recent years. Currently system architectures are service oriented i.e. they offer number of services. All such common services are grouped together and are available as a domain called as service domain. One such service domain of our interest is LBS (location based service). The service of our interest is tracking. Tracking of moving objects is done in applications like surveillance systems, human computer interactions, object recognition, navigation systems etc. In real world, 3D, the object which we want to track is called as object of interest (OOI). Tracking has been a difficult task to apply in congested situations due to inaccurate segmentation of objects. Common problems of erroneous segmentation are long shadows, partial and full occlusion of objects with each other and with stationary items in the scene. Difficulties in tracking objects can arise due to abrupt object motion, changing appearance patterns of both the object and the scene, nonrigid object structures, object-to-object and object-to-scene occlusions, and camera motion. In this paper we analyze different approaches for moving object tracking and detection. Keywords: Multiple moving object tracking, background modeling, morphology, target localization and representation, visual surveillance.
Semantic segmentation is the task of classifying each and every pixel in an image into a class as shown in the image below. Here you can see that all persons are red, the road is purple, the vehicles are blue, street signs are yellow etc.

Object recognition is the challenging problem in the real world application. Object recognition can be achieved through the shape matching. Shape matching is preceded by i) detecting the edges of the objects from the images. ii) Finding the correspondence between the shapes. iii) Measuring the dissimilarity between the shapes using the correspondence. iv) Classifying the object into classes by using this dissimilarity measures. In order to solve the correspondence problem, we attach a descriptor, the shape context, to each point. The shape context at a reference point captures the distribution of the remaining points relative to it, thus offering a globally discriminative characterization. Corresponding points on two similar shapes will have similar shape contexts. The one to one correspondence is achieved through the cost based bipartite graph matching. The cost matrix is reduced through Hungarian algorithm. The dissimilarity between the two shapes is computed using Canberra distance. The nearest neighbor classifier is used to classify the objects with the matching error. The results are obtained using the MATLAB for MINIST hand written digits.

GRAY SCALE IMAGE SEGMENTATION USING OTSU THRESHOLDING OPTIMAL APPROACHJournal For Research
Image segmentation is often used to distinguish the foreground from the background. Image segmentation is one of the difficult research problems in the machine vision industry and pattern recognition. Thresholding is a simple but effective method to separate objects from the background. A commonly used method, the Otsu method, improves the image segmentation effect obviously. It can be implemented by two different approaches: Iteration approach and Custom approach. In this paper both approaches has been implemented on MATLAB and give the comparison of them and show that both has given almost the same threshold value for segmenting image but the custom approach requires less computations. So if this method will be implemented on hardware in an optimized way then custom approach is the best option.
Robust Clustering of Eye Movement Recordings for QuantiGiuseppe Fineschi
Characterizing the location and extent of a viewer’s interest, in terms of eye movement recordings, informs a range of investigations in image and scene viewing. We present an automatic data-driven method for accomplishing this, which clusters visual point-of-regard (POR) measurements into gazes and regions-ofinterest using the mean shift procedure. Clusters produced using this method form a structured representation of viewer interest, and at the same time are replicable and not heavily influenced by noise or outliers. Thus, they are useful in answering fine-grained questions about where and how a viewer examined an image.

Kandemir Inferring Object Relevance From Gaze In Dynamic ScenesKalle
As prototypes of data glasses having both data augmentation and gaze tracking capabilities are becoming available, it is now possible to develop proactive gaze-controlled user interfaces to display information about objects, people, and other entities in real-world setups. In order to decide which objects the augmented information should be about, and how saliently to augment, the system needs an estimate of the importance or relevance of the objects of the scene for the user at a given time. The estimates will be used to minimize distraction of the user, and for providing efficient spatial management of the augmented items. This work is a feasibility study on inferring the relevance of objects in dynamic scenes from gaze. We collected gaze data from subjects watching a video for a pre-defined task. The results show that a simple ordinal logistic regression model gives relevance rankings of scene objects with a promising accuracy.
Semi-Supervised Method of Multiple Object Segmentation with a Region Labeling...sipij
Efficient and efficient multiple object segmentation is an important task in computer vision and object recognition. In this work; we address a method to effectively discover a user’s concept when multiple objects of interest are involved in content based image retrieval. The proposed method incorporate a framework for multiple object retrieval using semi-supervised method of similar region merging and flood fill which models the spatial and appearance relations among image pixels. To improve the effectiveness of similarity based region merging we propose a new similarity based object retrieval. The users only need to roughly indicate the after which steps desired objects contour is obtained during the automatic merging of similar regions. A novel similarity based region merging mechanism is proposed to guide the merging process with the help of mean shift technique and objects detection using region labeling and flood fill. A region R is merged with its adjacent regions Q if Q has highest similarity with Q (using Bhattacharyya descriptor) among all Q’s adjacent regions. The proposed method automatically merges the regions that are initially segmented through mean shift technique, and then effectively extracts the object contour by merging all similar regions. Extensive experiments are performed on 12 object classes (224 images total) show promising results.
Feature Extraction for Image Classification and Analysis with Ant Colony Opti...sipij
The problem of structure extraction from the image which contains many clustered objects is a challenging one for high level image analysis. When an image contains many clustered objects overlapping of objects can cause for hiding the structure. The existing segmentation techniques for better understanding, not able to the address the constituent parts of the image implicitly. The approaches like multistage segmentation address to some extent, but for each stage a separate structure is extracted, and thus causes for the ambiguity about the structure. The proposed approach called Ant Colony Optimization and Fuzzy logic based technique resolves this problem, and gives the implicit structure, that meets with original structure. The segmentation approach uses the swarm intelligence technique based on the behavior of the ant colonies. The segmentation is the process of separating the non-overlapping regions that constitute an image. The segmentation is important for structured and non-structured image analysis and classification for better understanding.
EXPLOITING REFERENCE IMAGES IN EXPOSING GEOMETRICAL DISTORTIONSijma
Nowadays, image alteration in the mainstream media has become common. The degree of manipulation is
facilitated by image editing software. In the past two decades the number indicating manipulation of
images rapidly grows. Hence, there are many outstanding images which have no provenance information
or certainty of authenticity. Therefore, constructing a scientific and automatic way for evaluating image
authenticity is an important task, which is the aim of this paper. In spite of having outstanding
performance, all the image forensics schemes developed so far have not provided verifiable information
about source of tampering. This paper aims to propose a different kind of scheme, by exploiting a group of
similar images, to verify the source of tampering. First, we define our definition with regard to tampered
image. The distinctive features are obtained by exploiting Scale- Invariant Feature Transform (SIFT)
technique. We then proposed clustering technique to identify the tampered region based on distinctive
keypoints. In contrast to k-means algorithm, our technique does not require the initialization of k value. The
experimental results over and beyond the dataset indicate the efficacy of our proposed scheme
Development of Human Tracking System For Video Surveillancecscpconf
Visual surveillance in dynamic scenes, especially for human and some objects is one of the
most active research areas. An attempt has been made to this issue in this work. It has wide
spectrum of promising application including human identification to detect the suspicious
behavior, crowd flux statistics, and congestion analysis using multiple cameras.
In this paper deals with the problem of detecting and tracking multiple moving people in a static
background. Detection of foreground object is done by background subtraction. Detected
objects are identified and analyzed through different blobs. Then tracking is performed by
matching corresponding features of blob. An algorithm has been developed in this perspective
using Angular Deviation of Center of Gravity (ADCG), which gives a satisfying result for segmentation of human object.

Abstract— In order to enable a computer to construct
and display a three-dimensional array, solid objects from
a single two-dimensional photograph, the rules and
assumptions of depth perception have been carefully
analyzed and mechanized. It is assumed that a
photograph is a perspective projection of a set of objects
which can be constructed from transformations of known
three-dimensional models, and that the objects are
supported by other visible objects or by a ground plane.
These assumptions enable a computer to obtain a
reasonable, three-dimensional description from the edge
information in a photograph by means of a topological,
mathematical process. A computer program has been
written which can process a photograph into a line
drawing .transform the line drawing into a three-
dimensional representation and, finally, display the three-
dimensional structure with all the hidden lines removed,
from any point of view. The 2-D to 3-D construction and
3-D to 2-D display processes are sufficiently general to
handle most collections of planar-surfaced objects and
provide a valuable starting point for future investigation
of computer-aided three-dimensional systems.
Keywords—Objects, Dimension, transformations and
construction.
I. INTRODUCTION
The problem of machine recognition of pictorial data has
long been a challenging goal, but has seldom been
attempted with anything more complex than alphabetic
characters. Many people have felt that research on
character recognition would be a first step, leading the
way to a more general pattern recognition system.
However, the multitudinous attempts at character
recognition, including my own, have not led very far.
The reason, of the study of abstract, two-dimensional
forms leads us away from, not toward, the techniques
necessary for the recognition of three-dimensional
objects. The perception of solid objects is a process which
can be based on the properties of three-dimensional
transformations and the laws of nature. By carefully
utilizing these properties, a procedure has been developed
which not only identifies objects, but also determines
their orientation and position in space.
Three main processes have been developed and
programmed in this report. The input process produces a
line drawing from a photograph. Then the 3 -D
construction program produces a three-dimensional object
list from the line drawing. When this is completed, the 3 -
D display program can produce a two-dimensional
projection of the objects from any point of view. In these
processes, the input program is the most restrictive,
whereas the 2-D to 3-D and 3-D to 2-D programs are
capable of handling almost any array of planar-surfaced
objects[1][2].
In order to implement the three-dimensional processing of
pictures, perspective effects must be considered. For this
reason, a four-dimensional, homogeneous system of
coordinates will be used. In this system a single 4 X 4
matrix can modify a position vector by a linear transform,
a translation, and a perspective transformation[3].
Although many books discuss this homogeneous system
of coordinates, their presentations are either incomplete or
too involved for our purposes.1
Therefore, the system is
explained in Appendix A. Without the notational
simplicity provided by using homogeneous
transformations, most of the following analysis would not
have been accomplished. It clearly depicted in the
following figure 1.1.

II. RELATED WORK
There have been numerous attempts to recognize simple
patterns by machine. There is the work with neuron-like
nets of threshold elements which divide the set of all input
patterns into a number of classes by correlating a set of
adaptive weights with some functions of multiple input
cells. For this type of system there may not be many
output classes and the transformations of the patterns
must be minimal or nonexistent. Because of these
restrictions, the patterns worked on so far have been
those, which worked on so far have been those which,
although complex, are not subject to much transformation
such as characters and spoken digits. This paper focus on
the recognition is typical and gives the other
references. This type of system would be of no value for
multiple object recognition, except perhaps for finding the
lines originally. That is, computation routines are
developed to extract the useful information from the
input, and their outputs are weighted to determine the
most likely output class. Here again a small set of outputs
is expected and characters were the patterns tested. One
problem with both these methods is that they were
intended for specific groups of abstract patterns, such as
characters, and not for the well-defined geometry of
photographs. They are better suited for looking at my
resultant list structure of objects and deciding whether a
group of objects is a chair or a table. There has been a
large volume of psychophysical research on human depth
perception and shape recognition[4].
Although the assumed size of objects such as playing
cards tended to vary, the subjects would judge the depth
reasonably well for normal-sized cards and
proportionately shorter for jumbo cards. Thus he, for one,
showed that the size of familiar objects is a good relative
depth cue and fair for absolute depth[5].
Recognition of forms, shapes, and objects is often
discussed from the Gestalt point of view, where shadowy
forms and plane geometry figures are the forms to be
recognized. They discuss contour following,
differentiating pictures, and some of the simple measures
of shape complexity. If they were discussing character
recognition, it might be reasonable to use these tools;
however, they say they are investigating "natural forms".
Rather, it defines the set of shapes which go with a single
perception. Perspective variations in a cube were tested
by Langdon in an experiment on 3-D solids. He found
that perspective plays only a minor part in the perception
of the size and depth and that the subjects always saw a
cube, even when it was badly distorted by the perspective
transform. The continual perception of a cube, even when
transformed, is consistent with Gibson's idea that shape
perception is and must be invariant under perspective
transformation. My idea of models also follows from this,
since each model represents an invariant percept, and can
be identified with any projection of itself.
III. OBSERVATION
The perception of depth in a monocular picture is based
completely upon the assumptions of the observer. Some
of the assumptions are about the nature of the real world
and some are based on the observer's familiarity with the
objects. Without these assumptions the picture is just
another two-dimensional image, whereas with them the
human is rarely confused about the depth relationships
represented in the picture. Since humans agree so closely
on their depth impressions, it is fair to assume that their
major assumptions are the same, and are therefore subject
to identification and analysis. The following is an attempt
to set down some of the likely assumptions and derive
what depth information can be obtained if they were used.
The first assumption is that the picture is a view of the
real world recorded by a camera or comparable device
and therefore that the image is a perspective
transformation of a three- dimensional field. This
transformation is a projection of each point in the viewing
space, toward a focal point, onto a plane. The
transformation will be represented with a homogeneous, 4
X 4 transformation matrix P such that the points in the
real world are transformed into points on the photograph.
The transformation depends on the camera used, the
enlargement printing process and, of course, the
coordinate system the real world is referred to. Let us fix
the real world coordinates by assuming that the focal
plane is the x = 0 plane and that the focal point is at x = f,
y = 0, z = 0. In order that the picture not is a reflection,
we choose the focal plane in front of the camera. Then the
objects seen will be in the x-half-space. Thus the focal
plane is really the plane of the print, not of the
negative. The following figure 1.2 shows this
arrangement.
Figure.1.2: Object Transformations
The three-dimensional field observed consists of a set of
solid objects which occupy a definite region of space.
Since we realize that it is usually possible to pick out the
lines which define the boundaries of the objects and their
surfaces, we shall assume that this has been accomplished

and that the picture has been reduced to a line drawing.
Because the objects are solid, we do not expect to see the
boundaries which are hidden from the focal point by
another solid. Second, we shall assume that the objects
seen could be constructed out of parts with which we are
familiar. That is, either the whole object is a
transformation of a preconceived model, or else it can be
broken into parts that are. The models could be anything
from a cube to a human body; the only requirement is that
we have a complete description of the three-dimensional
structure of each model. The transformation from the
model to the real world object will be a suitably restricted
homogeneous transformation matrix R. We must allow an
arbitrary rotation and translation of the model in order to
position it properly in space. We should also like to allow
three degrees of freedom for size change of the model so
that a cube model can represent any parallelepiped. So far
we have allowed nine degrees of freedom. The 4 X 4
matrix R can allow 15 degrees of freedom since it has 16
elements and the total scale of the matrix is arbitrary in
the homogeneous coordinate system. The last six degrees
of freedom represent skew and perspective deformations.
Skew deformations are size changes in the x-, y-, and z-
directions after the model has been rotated, and will
change the sides of a cube to parallelograms. A
perspective deformation is most easily visualized as a
compression of one end of the model. Objects that have
been de- formed in either way are not usually considered
to be simple instances of the model. Furthermore, objects
deformed in these ways could be constructed from smaller
parts, so it is not necessary to allow skew and perspective
deformations.
It allow perspective deformation and still obtain a unique
transform R from the picture; therefore, we require the top
three elements in the last column of R to be zero. Skew
variations can be allowed if we maintain very high
accuracy in our computations, so our derivation will allow
them, but later on they will be eliminated.
IV. CONCLUSION
Let us say that we are given a picture of a parallelepiped
and it has been reduced to a line drawing. It finds the
interior polygons, which correspond to the surfaces of the
object. There will normally be three quadrilaterals visible.
These polygons all come together at one point, which can
be used for a reference point. If we look through our list
of models, we find that a cube and perhaps other models
have three quadrilaterals about one point. Therefore, we
can pick a point in the cube model which has the proper
polygons around it, pick a polygon from both the cube
and the picture as starting points, and proceed to list
topologically equivalent point pairs.
