SMART WATER RING SCANNING SYSTEM AND METHOD USING PICTURE QUALITY IMPROVING FACTOR AND VIDEO CODING/DECODING SYSTEM AND METHOD USING THE SAME

摘要

PURPOSE: A smart water ring scanning system and method using a picture quality improving factor and a video coding/decoding system and method using the scanning system and method are provided to offer images suitable for the human visual system. CONSTITUTION: A water ring scanning system applied to a video encoding/decoding system includes a water ring generation position determining unit(61), a water ring position determining unit(69), and a water ring quality factor determining unit(63). The water ring generation position determining unit determines a water ring generation position in a video frame. The water ring position determining unit decides the i-th water ring position surrounding the water ring generation position. The water ring picture factor determining unit determines a water ring quality factor according to image region significance of the water ring generation position and the water ring position.
