%X 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 t...
