关于自适应窗口算法的描述，很详细，是最经典的自适应窗口算法，值得学习-We present a method to select an appropriate window by

evaluating the local variation of the intensity and the disparity.

We employ a statistical model of the disparity distribution within

the window. This modeling enables us to assess how disparity

\ariation, as well as intensity variation, within a window affects

the uncertainty of disparity estimate at the center point of the

window. As a result, we can devise a method which searches for

a window that produces the estimate of disparity with the least

uncertainty for each pixel of an image: the method controls not

only the size but also the shape (rectangle) of the window.
