    [[abstract]]Compressed media are vulnerable to channel errors during transmission, and protection of compressed media would be much required. In this paper, we employ block compressed sensing (BCS) for compression. We apply the inherent characteristics of original image content to aid the data protection performance for BCS. Image blocks are classified into active and smooth ones, and different protection schemes are applied. With active blocks, we protect with multiple description coding (MDC), while with smooth blocks, we perform the least absolute shrinkage and selection operator (LASSO). Both schemes can be worked together or be performed independently for data protection. Simulation results have pointed out the enhancements with image-adaptive classification of blocks for error resilient transmission of block compressed sensing.[[notice]]補正完
