Figure 5From: K-cluster-valued compressive sensing for imaging(a) The reconstruction error of Figure 4 measured by PSNR. In this figure, the PSNR (vertical axis) is shown along with various measurement number and the values at the horizontal axis indicate how many times of sparsity level S. (b) The results of PSNR output by K-cluster-valued CS with various cluster numbers K. The measurement number M here is set to be 3S.Back to article page
