It gets a BW image as input. The output are the displacements of the pixels along the X and Y directions. Keep into account that the output are images in floating-point format. The image displays expect such types of image to assume values in the range 0.0-1.0, however, the output of the Optical flow block exceeds such range (e.g., if the X displacement is from right to left, the number is less then zero). Thus, to properly display the outputs of the block you have to rescale the image such that it is in range [0.0-1.0].
