Description: Most motion-based tracking algorithms assume that objects undergo rigid motion, which is most likely disobeyed in real world. In this paper, we present a novel motion-based tracking framework which makes no such assumptions. Object is represented by a set of local invariant features, whose motions are observed by a feature correspon-
dence process. A generative model is proposed to depict
the relationship between local feature motions and object
global motion, whose parameters are learned efciently by
an on-line EM algorithm. And the object global motion is estimated in term of maximum likelihood of observations.Then an updating mechanism is employed to adapt object representation. Experiments show that our framework is
exible and robust in dealing with appearance changes,background clutter, illumination changes and occlusion

Description: Patent:SYSTEM AND METHOD FOR 3D OBJECT RECOGNITION. The present invention provides a system and method for recognizing a 3D object in a single camera image and for determining the 3D pose of the object with respect to the camera coordinate system. In one typical application, the 3D pose is used to make a robot pick up the object. A view-based approach is presented that does not show the drawbacks of previous methods because it is robust to image noise, object occlusions, clutter, and contrast changes. Furthermore, the 3D pose is determined with a high accuracy. Finally, the presented method allows the recognition of the 3D object as well as the determination of its 3D pose in a very short computation time, making it also suitable for real-time applications. These improvements are achieved by the methods disclosed herein.

Description: We present an object class detection approach
which fully integrates the complementary strengths offered
by shape matchers. Like an object detector, it can
learn class models directly from images, and can localize
novel instances in the presence of intra-class variations,
clutter, and scale changes. Like a shape matcher,
it finds the boundaries of objects, rather than just their
bounding-boxes. This is achieved by a novel technique
for learning a shape model of an object class given images
of example instances. Furthermore, we also integrate
Hough-style voting with a non-rigid point matching
algorithm to localize the model in cluttered images.
As demonstrated by an extensive evaluation, our
method can localize object boundaries accurately and
does not need segmented examples for training (only
bounding-boxes).

Description: One of the most popular approaches to detect lines is based on the Radon transform (RT). But in real-world applications
RT-based approach suffers the noise and clutter, because they decrease the sharpness of the local maximums.
In this paper we suggest a new approach to computational effective line detection using the Weighted Radon Transform
(WRT). The suggested WRT-based approach uses gradient direction information, so only the differences that are
perpendicular to the line direction are integrated to make a local maximum corresponding to the line.
The theoretical and experimental studies show the effectiveness of the WRT-based line detection. The suggested WRTbased algorithm can be effectively implemented in real-time systems using parallelization and FFT-based techniques.
