Image Enhancement Using a Modified Histogram Equalization
Image enhancement algorithms based on Histogram equalization (HE) often fall short to maintain the image quality after enhancement due to quantum jump in the cumulative distribution function (CDF) in the histo...

Fast Reconstruction Technique for Medical Images Using Graphics Processing Unit
In many medical imaging modalities, the Fast Fourier Transform (FFT) is being used for the reconstruction of images from acquired raw data. The objective of the paper is to develop FFT and Inverse FT algorithm...

Minimum Distortion Data Hiding
In this paper a new steganographic method is presented with minimum distortion, and better resistance against steganalysis. There are two ways to control detectability of stego message: one is less distortion,...

Concurrent Covert Communication Channels
This paper introduces a new steganographic technique in which a set of concurrent hidden channels are established between a sender and multiple receivers. Each channel is protected by a separate key. The metho...
