Secure end-to-end voice communication is crucial, but it has several issues. Researchers in
this field can benefit from a review paper with broader evaluation parameters than existing …

Sign Language is a natural language which deaf community uses for communication. Sign
Language (SL) is a subset of gestures or signs made with fingers, hands, arms, eyes, and …

In recent years, reversible data hiding (RDH) has attracted extensive attention from the
academia. Besides RDH for uncompressed images, RDH for compressed images with …

In this paper, we propose a secret group-key generation scheme in physical layer, where an
arbitrary number of multi-antenna LNs (LN) exist in mesh topology with a multi-antenna …

A novel grayscale image hiding scheme that is capable of hiding multiple secret images into
a host image of the same size is proposed in this paper. The secret images to be hidden are …

Background The frequency-following response (FFR) is a scalp-recorded
electrophysiological potential reflecting phase-locked activity from neural ensembles in the …

The k-means clustering algorithm is a commonly used algorithm for palette design. If an
adequate initial palette is selected, a good quality reconstructed image of a compressed …

In this paper, a fast codebook search algorithm that is equivalent to the full search algorithm
for image vector quantization is proposed. The image encoding procedure of VQ needs to …

This paper proposes a high-capacity image-hiding scheme based on an adaptive index.
Data-hiding based on vector quantization (VQ) is a technique for hiding data in the VQ index …

Sign language is a medium of communication of Divyangjans (Deaf and mute people). Sign
language can be used for effective communication only if understood by both the people …
