ABSTRACT:
A method and system are provided for indicating a change between a first image and a second image. In a first aspect, a sequence of images is sensed (304, 310) including the first and second image. The first image is previous in the sequence to the second image. Each image previous in the sequence to the second image is processed generating a first processed image (312). The first processed image and the second image are then processed generating a second processed image (316, 312). The first processed image and the second processed image are then processed generating an optical flow field (314). The optical flow field shows the change between the first image and the second image. In a second aspect, a first sequence of images including the first image is sensed (206). A second sequence of images including the second image is sensed (206). The first sequence is processed generating a first processed image (210). The second sequence is also processed generating a second processed image (208). The first processed image and the second processed image are then processed generating an optical flow field (216). This optical flow field also indicates the change between the first image and the second image.
