Abstract

An optical flow estimation apparatus with subpixel resolution includes a data cost calculation unit ( 1 00) for computing a pixel-resolution data cost and a subpixel-resolution data cost for each node with respect to a first and a second input image successive in time; a message calculation unit ( 1 10) for iteratively computing a pixel-resolution message and a subpixel-resolution message between the node and each neighboring node based on the pixel-resolution data cost and the subpixel-resolution data cost, respectively; and a result output unit ( 120) for estimating a pixel-resolution optical flow vector of each node based on the pixel- resolution data cost of the node and the pixel-resolution messages received from neighboring nodes of the node. The result output unit ( 120) estimates a subpixel-resolution optical flow vector of each node based on the subpixel-resolution data cost and the subpixel-resolution messages which are computed by using the pixel-resolution optical flow vector of the node.
