Stereo Image Reversible Watermarking
In this paper, a new reversible watermarking method is presented that reduces the size of a stereoscopic image pair while keeping its content visible. The proposed technique embeds the disparity compensated difference and the disparity vectors of the stereo pair into the reference image, halving its total capacity. The residual is usually lossy compressed before embedding because the embedding ...
متن کاملImage Watermarking for Tamper Detection
We propose an oblivious watermarking technique for tamper detection in digital images. By comparing correlation values from different portions of the image, the technique enables us to distinguish malicious changes, such as replacing / adding features from nonmalicious changes resulting from common image processing operations. The technique can be implemented with small memory and computational...

متن کاملColour Contribution for Stereo Image Matching
We examine the contribution of colour for the computation of depth maps from a stereo pair of colour aerial images. As a matter of fact we propose an original method based on fusion theory to compute dense and reliable depth maps. The fusion is directly applied on correlation curves obtained for each colour channel. In order to evaluate the quality of the elevation map, we compare our results t...
متن کاملA Hybrid Method for Stereo Image Matching
The accuracy of the 3D models of the Earth surface based on stereoscopic image pairs depends on the accuracy of corresponding points located in both images. Area-based automatic image matching combined with a region-growing technique are able to provide a dense and accurate grid of corresponding points. However the region-growing process may stop at image patches where the xparallax is suddenly...
