Research on Joint Watermarking & Lossless Compression for Image

Bharti Verma ^[2] | Somesh Dewangan ^[3] | Sachin Harne

Abstract: In recent times, the transmission and storage of digital documents/information over the unsecured channel ar huge issues and nearly all of the digital documents ar compressed before they & #039, re hold on or transmitted to avoid wasting the information measure necessities. There ar several similar process operations performed throughout watermarking and compression that cause process redundancy and time delay. This demands development of joint watermarking and compression theme for varied transmission contents. during this paper, we tend to propose a way for image watermarking throughout JPEG compression to handle the best trade off between major performance parameters as well as embedding and compression rates, hardiness and embedding alterations against totally different familiar signal process attacks. The performance of the planned technique is extensively evaluated within the sort of peak signal to noise quantitative relation (PSNR), correlation, compression quantitative relation and execution time for various distinct circular function remodel (DCT) blocks and watermark sizes. Embedding is completed on DCT coefficients mistreatment additive watermarking.
