TLDR
An effective algorithm has been introduced which would embed secret message data, scrambled by Arnold Transform, in frequency domain using the quantization coefficient modification in Discrete Cosine Transform (DCT).Abstract:
To ensure reliability and integrity in information transmission, image steganography is cutting edge technology in today's digital world. It can be implemented in spatial, time and frequency domain. In this research article, an effective algorithm has been introduced which would embed secret message data, scrambled by Arnold Transform, in frequency domain using the quantization coefficient modification in Discrete Cosine Transform (DCT). At first the cover image is split into blocks, then two dimensional DCT is applied on each image block and transformed secret message is inserted by analyzing mid-band coefficients of DCT. After the successful transmission of the cover image to the recipient, the secret message can be effectively recovered in high quality from the Stego image.read more

Image quality assessment: from error visibility to structural similarity
TL;DR: In this article, a structural similarity index is proposed for image quality assessment based on the degradation of structural information, which can be applied to both subjective ratings and objective methods on a database of images compressed with JPEG and JPEG2000.
Image Compression Using the Discrete Cosine Transform
TL;DR: Some simple functions to compute the discrete cosine transform and how it is used for image compression are developed to illustrate the use of Mathematica in image processing and to provide the reader with the basic tools for further exploration of this subject.
