摘要：
Differential pulse-code modulation is coupled with uniform scalar quantization to provide block-based quantized compressed sensing of images. Experimental results demonstrate significant improvement in rate-distortion performance as compared scalar quantization used alone in several block-based compressed-sensing reconstruction algorithms. Additionally, rate-distortion performance superior to that of alternative quantized-compressed-sensing techniques relying on optimized quantization or reconstruction is observed.
