Design of Adaptive Watermarking Algorithms for Video Signals Using Subjective Tests
Yuting Su · 2009
By introducing the subjective tests,a subjective optimized adaptive video watermarking algorithm was pre-sented.This paper described an adaptive watermarking algorithm which is based on measured visibility thresholds of the impairments brought by watermarking.The visibility thresholds were determined by subjective tests.Constructions of the watermarking scheme were carried out such that the embedding strength is maximized without exceeding the mea-sured visibility thresholds.Experimental results show that the presented watermarking scheme achieves comparatively high detection rate than spatial non-adaptive watermarking scheme and the simple human visual system based adaptive watermarking scheme.
