2-D DFT of two dimensional finite extent sequences.

2-D DFT and Convolution
The DFT can be computed with a fast algorithm and it is sometimes beneficial to do the convolution of two sequences A (M1 N1) and B (M2 N2) via point DFTs. Speed improvements are only possible if both sequences have large dimensions. Otherwise convolutions are better implemented via the convolution sum.

This Image Steganography in frequency domain using DFT project was developed in Matlab tool for final year ECE & EE students, By using Steganography and DFT concept we will hide secrete image/message in the cover image. For encryption of the data and images we will use data encoding algorithm.In today's communication world, data sharing and transfer is increasing exponentially. The threat of an attacker accessing secret information has been an ever existing concern for the data communication experts. Cryptography and steganography are the mos ....etc
