In this paper we present an adaptive compressed sensing (CS) frame-work for depth map compression using a family of graph-based transforms (GBT). To improve overall performance we propose a greedy algorithm that selects for each block a GBT that minimizes a metric that takes into consideration both the edge structure of the block and the characteristics of the CS measurement matrix, using an estimate of average mutual coherence. As compared to coding using H.264/AVC, the proposed approach applied to intra-frames shows an average of 39 % bitrate savings or 3.8 dB PSNR gain for views rendered using a depth image based rendering (DIBR) technique
