Abstract
본 발명은 윤곽이 부호화된 이전의 영상을 윤곽이 부호화되지 않은 현재의 원 영상과 비교하여 영상의 변형으로 인한 악영향을 최소화할 수 있도록 한 윤곽선 부호화에서의 움직임 추정방법에 관한 것으로, 이는 하기와 같은 비교동작을 수행하여 영역 부호화시 생긴 영상의 변형으로 인한 악영향을 최소화시킴으로써, 보다 선명한 윤곽의 부호화를 통해 부호화로 인한 화질열화를 방지한 것이다.The present invention relates to a motion estimation method in contour coding, which compares a previous image having a contour coded with a current original image without a coded contour, thereby minimizing adverse effects due to deformation of the image. By performing the comparison operation to minimize the adverse effect due to the deformation of the image generated during the region encoding, the image quality degradation due to the encoding is prevented through the encoding of the sharper contour.
(여기에서, PBi는 윤곽이 부호화된 이전의 영상에서 임의의 영역내에 있는 픽셀 중 i번째 픽셀, PCi는 윤곽이 부호화되지 않은 현재의 영상에서 임의의 영역내에 있는 픽셀 중 i번째 픽셀, i는 그 영역내의 픽셀 갯수, th1, th2는 임의의 경계값을 각각 의미함.)(Wherein, P Bi is the i-th pixel of the pixels within any region in the previous image in which the contour is coded P Ci is the i-th pixel of the pixels within a certain region in a current picture is not the contour is coded, i Is the number of pixels in the area, and th1 and th2 mean arbitrary boundary values respectively.)
