Abstract
When the corresponding position of each pixel in stereo video pair is searched, a fixed pixel is set in one side video and the corresponding pixel is set in the other side video. Then, a window is set around the fixed pixel in one side video and a same size window is set around the corresponding pixel in the other side video. Selectable and plural kinds of window size are prepared at that moment. Pixel values are compared with each other respectively. The MDL standard value is adopted as for an evaluation standard. In the comparison, the smaller the MDL standard value of the window size, the more suitable the window size. All pixel values in the window are used for parameters to calculate the MDL standard value. The MDL standard value contains the value which is equivalent to error quantity in case of comparing each pixel in the window, it also indicates resemblance of the video picture in the windows. The corresponding pixel having the minimum MDL standard value is supposed to be the corresponding position of the fixed pixel. In this way, searching the corresponding point can be performed based on the comparison results in the most suitable model.
