Abstract:	Delivery of compressed images forms an inevitable part in multimedia communications. In addition to conventional compressed schemes in international standards, we employ the newly developed block-based compressed sensing for compression at the encoder, and deliver compressed image over channels. Channel errors may cause degradation to reconstructed qualities at the decoder. We make use of inherent characteristics and color plane correlations of image contents to help enhance the reconstruction quality after delivery. We choose error protection and error regression schemes, and the integration of the two, to look for enhanced reconstruction quality. Experimental results have demonstrated that error protection or regression have revealed their capabilities, and the integration performs the best among different experimental settings. Proposed schemes have demonstrated their advantages to reach enhanced quality of reconstructed images.
