Human eyes have different sensitivity to different frequency components of image signals, typically, low frequency components are relatively more crucial to the perceptual quality of images than high frequency components. Based on this observation, we propose a novel sampling scheme for compressive sensing framework by designing a weighting scheme for the sampling matrix. By adjusting the weighting coefficients, we can tune the structure of the sampling matrix to favor the frequency componentsdoi:10.1109/icme.2009.5202443 dblp:conf/icmcs/YangAFWT09 fatcat:3gmhumgltzbvzix5p6v6tz3eyu
