Image is one of the most important forms of information. In this paper, two public key encryption systems are proposed to protect images from various attacks. Both systems depend on generating a chaotic matrix (I) using multiple chaotic maps. The par

Denoising is one of the main issues in digital image processing systems. This paper presents a new idea to improve the Peak Signal to Noise Ratio (PSNR) of the denoised image by dividing the image into many blocks then a variable threshold is set acc
