Fig. 3From: Robust video steganography for social media sharing based on principal component analysisThe steganographic framework based on PCA selection. EDY and EDU are the embedding domains constructed from the Y and U components, respectively. SI is the side information that labels PCA-selected regions. Y, U, and V represent the luminance and chrominance components. Ystego and Ustego are the steganographic version of Y and U, respectivelyBack to article page
