Universal share-based two-in-one multi-image secret sharing scheme by rotating random grids
EURASIP Journal on Information SecurityMulti-image secret sharing (MSS) scheme for two decoding options by employing universal share is discussed in this manuscript. One decoding option is piling of shares to get a secret image preview and the other option needs computation of shares to get a

An Image Multiresolution Representation for Lossless and Lossy Compression
, 1993 We propose a new image multiresolution transform that is suited for both lossless (reversible) and lossy compression. The new transformation is similar to the subband decomposition, but can be computed with only integer addition and bit-shift operations.
