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.

Segmentation of ship target under complex background has important research significance in long-range ship tracking and identification
and an adaptive segmentation algorithm is proposed according to background images with different complexity. Local complexity of image is first calculated in this algorithm
and then the original image is preprocessed with different de noising methods according to local complexity
finally the image is binarized based on local complexity and the target is segmented. The experiment results indicate that the algorithm is adaptive and can meet the requirements of real-time processing
which lays a foundation for ship target detection under complex background. 2010 IEEE.

Image segmentation is the first essential and important step of low level vision. This paper proposes a novel algorithm for adaptive image segmentation
it can be applied in many conditions
based on thresholding technique and segments merging according to their characteristics combine with spatial position. Our earlier work of getting the entire information of the histogram could help choose the multiple thresholds. However
including complex target segmented. We describe the algorithm in detail and perform simulation experiments. The computation based on pixels can fully parallel processing to save time. 2006 IEEE.
not all the peaks of the histogram correspond to obvious structural unit in the image. Spatial information must be involved. This paper also suggests subjoining segments matching for video image tracking. They will give great help to image segmentation. The proposed algorithm can meet the real-time requirement and lead to higher segmentation accuracy
some types of texture can also be segmented well
