Based on the theoty of statistical dctection and research on distribution of dct coefficiefits , the chapter 3 proposes a robust 3d motion blind watermark detection algorithin , which is a sign correlation detection scheme 第三章基于統(tǒng)計(jì)檢測(cè)理論與dct變換系數(shù)分布的研究,提出一個(gè)魯棒的三維運(yùn)動(dòng)盲水印檢測(cè)算法,它是一個(gè)dct變換域上的符號(hào)相關(guān)性檢測(cè)算法。
