This paper presents a new approach for non-blind watermarking of still gray level images in contourlet domain. It uses the Human Visual System (HVS) characteristic, and an innovative entropy based approach to create an efficient watermarking scheme. It decomposes original image in contourlet domain in four hierarchical levels and watermarks it with a logo(More)
A new approach for non-blind watermarking of still gray level images in the wavelet domain. The method uses the human visual system (HVS) characteristic, and an innovative entropy based approach to create an efficient watermarking scheme is presented in this paper. It decomposes original image in DWT domain in to three hierarchical levels and watermarks it(More)
As the volume of digital video captured and stored continuesto increase, research efforts have focused on contentmanagement systems for video indexing and retrieval applications.A first step in generic video processing is shot boundary detection. This paper addresses a novel algorithm for abrupt shot (cut/pause) detection - especially on frames with similar(More)
The aim of this research is to investigate the possibility of using medical image information to extract unique features and classify different patients’ organ tissues, such as the prostate, based on concepts related to what is already done in iris recognition. This paper therefore presents a new approach in medical imaging, an organ recognition(More)
