摘要
Luminance contrast was used to compute the saliency value of input all-sampling image, and the adaptive measurement wais realized depending on the saliency value of image block. At the reconstruction side, the saliency value of each block was estimated by using varying block measurement rates, and then these saliency values were used to weight the objective function of reconstruction model in order to enforce the quality improvements of high-saliency blocks. Experimental results indicate that the reconstructed image by the proposed algorithm has a better objective quality when comparing with several traditional ones, and its edge and texture details are better preserved, which guarantees the better subjective visual quality. Besides, the proposed method has a low computational complexity of measurement and reconstruction. © 2016, Editorial Board of Journal of Huazhong University of Science and Technology.
