An algorithm based on weight image analysis is proposed for adaptive deformation estimation of moving target in mean-shift tracking method. At the first
we get the weight image from the target candidate region. Then
we analyze the differences between the object and background. According to that
the area estimation of the target can be converted into the image segmentation task. To realize the adaptive segmentation and estimation
we define the threshold as the maximum variance between object and background. Combining the estimated area and covariance matrix
we can estimate the width
height and orientation of the object. The experimental results on three representative video sequences validate its robustness to the deformable estimation of the targets. 2010 IEEE.

A new method of affine object recognition and affine parameters estimation is presented. For a real-time image and a group of templates
in addition
firstly
on the basis of correct recognition
we segment the object regions in them and compute their covariant matrices. Secondly
it can estimate affine parameters exactly
normalize the ellipse regions defined by covariant matrices to circle regions to get rotational invariants
and the estimated error is within 3%. 2008 IEEE.
and compute the similarity function value between rotational invariants of real-time image and every template respectively. Then compare the values with threshold set in advance
if more than one value is larger than threshold
take the corresponding templates as candidates
and compute affine matrix between real-time image and every candidate. Finally
transform the realtime image with every affine matrix and match the result with corresponding candidate by classical matching methods. Experimental results show that the presented method is robust to illumination
with low computational complexity
and it can realize recognition of different affine objects
