A Dual-Mode Index Modulation Scheme With Gray-Coded Pairwise Index Mapping

IEEE Communications Letters, 2018
In this letter, we propose a single-carrier (SC) dual-mode (DM) index modulation scheme with Gray-coded pairwise index mapping. To improve the index error rate performance of DM schemes, we apply Gray-coding to the mapping of modulation patterns. The error propagation within each symbol group in DM schemes can also be avoided due to the pairwise ...

VQ-BASED GRAY WATERMARK EMBEDDING SCHEME WITH GENETIC INDEX ASSIGNMENT

International Journal of Computational Intelligence and Applications, 2004
A digital watermarking scheme based on vector quantisation (VQ) for gray watermark is proposed. It begins with the procedure of encoding the gray watermark, and embeds the encoded indices into the cover image in VQ domain then. To improve the performance of the watermarking scheme, a genetic index assignment (GIA) procedure, which modifies the signal ...

Low Complexity Gray-scale Image Compression Method Using Index-Based Approach

2021 Asian Conference on Innovation in Technology (ASIANCON), 2021
Images consume more space when stored and use a lot of bandwidth during transmission. Hence, an image compression reduces storage space required, and time to transmit an image by making effective usage of bandwidth. In this paper, a simple image compression method using an index-based approach is proposed.

Gray System Model for Estimating the Pavement International Roughness Index

Journal of Performance of Constructed Facilities, 2005
The international roughness index (IRI) is a measurement of pavement roughness that is widely accepted for evaluating pavement serviceability, especially its riding quality. Generally, as the age of pavement increases, its condition deteriorates and its IRI value increases.
