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.

This paper discusses image's object edge extracting of threshold value. First
this paper introduces fundamental principle of gray image object edge extracting
after discussing the influence of object edge image's gray scale distributing characteristic and choice of threshold value to character extracting and target identification
we bring forward a sort of method
which using object edge fuzzy taxonomy and maximum fuzzy entropy theory to auto choose threshold value in the case that membership function is given
then we have a test of threshold value segmentation to edge gray image in different contrast
the result indicates this method has preferable scene adaptive faculty.
