Share Audio Cryptography Using DCT Transform

An Effective and secure protection of sensitive information is the primary concern in communication systems or network storage systems, it is important for any information process to ensure data is not being tampered. To achieve confidentiality and integrity of multimedia information, various Secret Sharing Schemes (SSS) have been developed.This thesis presents a (2,n) threshold Secret Sharing Scheme, which is one of the types of SSS and a special  kind of  (k, n) threshold scheme.

Texture regcognsion using density distribution method

Abstract:

The recognition process is an important task in many applications of computer image analysis based on color or texture features. In this research, a texture recognition system has been introduced.The first stage
is called the preprocessing stage. In this stage, a number of color transforms have been done on the training images to produce a set of bands (R, G, B, Gray, Y, I, Q, H, S, and V bands). Fromthese bands, two
