A chaos based image encryption and lossless compression algorithm using hash table and
Chinese Remainder Theorem is proposed. Initially, the Henon map is used to generate the …

A chaos-based joint image compression and encryption algorithm using discrete cosine
transformation (DCT) and Secure Hash Algorithm-1 (SHA-1) is proposed. As SHA-1 is fast …

A joint lossless image encryption and compression scheme based on integer wavelet
transform (IWT) and set partitioning in hierarchical trees (SPIHT) is proposed to achieve …

Sensory systems must reduce the transmission of redundant information to function
efficiently. One strategy is to continuously adjust the sensitivity of neurons to suppress …

Diabetic Retinopathy (DR) is one of the leading causes of blindness in the industrialized
world. Early detection is the key in providing effective treatment. However, the current …

A new DNA sequence-based data-hiding scheme is presented in this paper. We establish
an injective mapping between one complementary rule and two secret bits in a message …

This paper proposes a new image compression and encryption scheme based on the
nearest-neighboring coupled-map lattices (NCML) and Non-uniform Discrete Cosine …

In this Ph. D. thesis, we study new methods to analyse digital fundus images of diabetic
patients. In particular, we concentrate on the development of the algorithmic components of …

This paper proposed several methods to transplant the compound chaotic image encryption
scheme with permutation based on 3D baker into image formats as Joint Photographic …

The discrete Fourier slice theorem is an important tool for signal processing, especially in
the context of the exact reconstruction of an image from its projected views. This paper …
