Lossless recovery is important for the transmission and storage of image data. In polynomial-based secret image sharing …, despite many previous researchers attempted to achieve lossless recovery, none of the proposed work can simultaneously satisfy … lossless recovery based on polynomial-based scheme and modular algebraic recovery. The major difference between the proposed …

Lossless recovery in visual secret share (VSS) is very meaningful. In this paper, a novel lossless recovery algorithm … pixel expansion. The condition of lossless recovery of a VSS is given by analyzing the XOR all columns of basic matrixes …

will be. Furthermore, it can realize lossless recovery with all the shares. It can be directly used to share grayscale …
