Abstract

Watermarks not specifically designed to be visible should be imperceptible to maintain image or video quality. Watermark characteristics that affect visibility include watermark magnitude, the visual masking model used to determine relative magnitude values, watermark frequency content, and the degree of temporal variation of the watermark between frames. Video characteristics that affect the visibility of a watermark include subject and camera motion, color, resolution, texture, and patterns. We have investigated the effects of these characteristics on watermark visibility for MPEG-1, MPEG-2, and both uncompressed and compressed high-definition video. The average watermark strength that can be added to a video is determined by increasing the average watermark magnitude through the sequence in order to observe the point at which the watermark becomes perceptible. The first artifact to become visible depends on video and watermark characteristics.
