Adaptive decoding for halftone orientation-based data hiding
Halftone image watermarking techniques that allow automated extraction of the embedded watermark data are useful in a variety of document security and workflow applications. The p...

Image dependent log-likelihood ratio allocation for repeat accumulate code-based decoding in data hiding channels
Error correction codes of suitable redundancy are used for ensuring perfect data recovery in noisy channels. For iterative decoding based methods, the decoder needs to be initiali...

List-Decoding Using The XOR Lemma
We show that Yao’s XOR Lemma, and its essentially equivalent rephrasing as a Direct Product Lemma, can be re-interpreted as a way of obtaining error-correcting codes with good l...

A Parallel Architecture for Hermitian Decoders: Satisfying Resource and Throughput Constraints
— Hermitian Codes offer desirable properties such as large code lengths, good error-correction at high code rates, etc. The main problem in making Hermitian codes practical is to...
