DOI: 10.1007/s11042-020-08925-3
Abstract: This paper proposes a new image steganographic method that effectively combines LSB embedding with Octa-PVD embedding. A cover image is divided into non-overlapping 3 × 3 sub-blocks, the n least significant bits of the center pixel of… read more here.

DOI: 10.1109/access.2023.3252888
Abstract: Hyperspectral Image reconstruction from RGB images is a low-cost and convenient alternative to acquiring hyperspectral images directly. The challenge in estimating the spectral response function and using it for generating the hyperspectral image data is… read more here.

DOI: 10.1109/tcomm.2022.3187791
Abstract: We propose a new family of spatially coupled product codes, called sub-block rearranged staircase (SR-staircase) codes. Each code block of SR-staircase codes is obtained by encoding rearranged preceding code blocks and new information blocks, where… read more here.

On the Decoding Performance of Spatially Coupled LDPC Codes With Sub-Block Access

DOI: 10.1109/tit.2022.3152104
Abstract: We study spatially coupled LDPC codes that allow access to sub-blocks much smaller than the full code block. Sub-block access is realized by a semi-global decoder that decodes a chosen target sub-block by only accessing… read more here.
