Fig. 6From: An adaptive random compressive partial sampling method with TV recoveryEvaluating the optimum \(\eta _2\) for \( \varPhi _\text{m}+M_{\text {c,d}}^p.\) The sensing ratio is \(\eta _1=40\%\) for both \( \varPhi _\text {r}\) and \( \varPhi _\text{m}+M_\text {{c,d}}^\text {p}\). The left column: the PSNR versus \(\eta _2\) for test images, respectively, and the right column: the SSIM versus \(\eta _2\) , respectivelyBack to article page
