Abstract

A study to have read does an improvement of an error restoration technology based on the edge direction interpolation that a stop image cared for inside frame correction more than with an image restoration way of a transfer error or with an aim. A way proposed to is based on edge direction detection method of a block utilizing the edge direction which will adjust a part damaged a sweater to a remaining part here. The rest of error pixel used non linear Midian filter for process later data information by the final stage and did interpolation. The examination result shows a good recuperation tendency and low accounts time of a way proposed to realization possibility of a real time image processing.

본 연구는 전송 오차의 이미지 복원에 관한 방법으로 정지영상 또는 내부프레임 정정을 위한 모서리 방향 보간법에 기초한 오차 복원 기술의 개선을 목표로 한다. 여기서 제안된 방법은 블록의 모서리 방향 검출 방법은 스웨터의 손상된 부분을 남아 있는 부분과 맞추어가는 모서리 방향을 이용하는 것에 근거한다 처리 후 데이터 정보에 남은 에러 픽셀을 마지막 단계로 비선형 미디안 필터를 사용하여 보간 하였다. 실험 결과는 제안된 방법의 높은 회복 성향과 낮은 계산 시간은 실시간 영상 처리의 실현 가능성을 나타낸다.
