본 논문에서는 비디오 시퀀스가 서로 다른 수준의 선명도를 갖는 대체 프레임으로 구성되는 특별한 경우에 대해 모션 샤프닝 현상을 시각적 마스킹의 한 형태로 설명할 수 있음을 보여줍니다. 선명도가 높은 프레임은 선명도가 낮은 후속 프레임의 모호성을 가리는 역할을 하여 전체 시퀀스의 지각 품질을 유지합니다. 시각적 마스킹 메커니즘을 차용하여 마스킹되는 프레임의 주관적 품질을 보존하는 최소 공간 주파수 조건을 도출하기 위한 정량적 모델을 공식화했습니다. 정량적 모델은 비디오 신호의 세 가지 기본 속성, 즉 동작 크기, 평균 휘도 및 각 주파수 구성 요소의 전력을 고려합니다. 이러한 특성의 변화에 대한 정신물리학적 반응은 간단한 기하학적 패턴의 비디오 시퀀스를 사용한 주관적 평가 테스트를 통해 얻습니다. 자연 비디오 시퀀스에 대한 주관적 실험에 따르면 시청자의 75% 이상이 원본 시퀀스와 정량적 모델을 사용하여 처리된 시퀀스를 구별하지 못하는 것으로 나타났습니다.

Abstract: In this paper, we show that motion sharpening phenomenon can be explained as a form of visual masking for a special case where a video sequence is composed of alternate frames with different level of sharpness. A frame of higher sharpness behaves to mask the ambiguity of a subsequent frame of lower sharpness and hence preserves the perceptive quality of the whole sequence. Borrowing the mechanism for visual masking, we formulated a quantitative model for deriving the minimum spatial frequency conditions which preserves the subjective quality of the frames being masked. The quantitative model takes into account three fundamental properties of the video signals, namely the size of motion, average luminance and the power of each frequency components. The psychophysical responses towards the changes of these properties are obtained through subjective assessment tests using video sequences of simple geometrical patterns. Subjective experiments on natural video sequences show that more than 75% of viewers could make no distinction between the original sequence and the one processed using the quantitative model.
