Improving the Visual Quality of Size-Invariant Visual Cryptography for Grayscale Images : An Analysis-by-Synthesis (AbS) Approach
In visual cryptography (VC) for grayscale image, size reduction leads to bad perceptual quality to the reconstructed secret image. To improve the quality, the current efforts are limited to the design of VC algorithm for binary image, and measuring the quality with metrics that are not directly rela...
