Abstract
The present invention relates to an apparatus and to a method for motion estimation-based encoding/decoding, which estimate a motion and perform an encoding operation based on a photo core transform and a photo overlap transform in a motion picture encoding process, and perform a motion compensation and a decoding operation in a motion picture decoding process, thereby removing the temporal and spatial redundancy of the motion picture. The video processing system according to the present invention comprises: a video encoding apparatus which transforms the received video based on a motion estimation through a photo core transform and a photo overlap transform, encodes the video by a variable length coding technique, and outputs a bit stream; and a video decoding apparatus which performs a motion compensation and a decoding operation on the bit stream received from the video encoding apparatus. The present invention enables a video reproduction or compression through a video codec of a low complexity even in a low performance mobile device, and prolongs the useful life of a battery.
