The Motion Detection and Depth Estimation Using the Pixel-Wise Matching of Optical Flow

Abstract

The detection of motion information is a fundamental research in the field of computer vision or moving picture analysis. In this paper, the precisely detecting method of optical flow is described. First, the optical flow constraint of gradient is calculated and optical flow vector is estimated using the pixel-wise matching procedure. Next, motion of the object is approximated using the parameter of affine-model. The use of these parameters improves the precision of optical flow. The validity of this method is confirmed by computer simulation. It is also examined that this method is further applied to the estimation of distance in depth.
