Abstract:This paper gives the choice of watermark domain in presence of the lossy compression. It is assumed that separation of watermark embedding domain from the processing (compression or decompression) domain improves the embedding capacity of the image. Improvement in the embedding capacity ultimately results into the improved robustness of the technique. We worked mainly with [...]

ABSTRACT
Watermarking in medical images is a new area of research and some works in this area have been reported world wide recently. Most of the works are on the tamper detection of the images and embedding of the Electronics Patient Record (EPR) data in the medical images. Watermarked [...]

ABSTRACT
In this paper, a content dependent visible watermarking scheme for video is proposed. We calculate the unsuitability contrary [1], to the focus region that catches user’s attention the most and embed a visible watermark to the region with the highest unsuitability. The watermark embedding is performed shot by shot, so that [...]
