Post-segmentation Approach for Lossless Region of Interest Coding
This paper presents a lossless region of interest coding technique that is suitable for interactive telemedicine over networks. The new encoding scheme allows a server to transmit only a part of a compressed image data progressively as a client requests it. This technique is different from region scalable coding in JPEG2000 since it does not define region of interest (ROI) when encoding occurs....
متن کاملLossless Region of Interest with Embedded Wavelet Image Coding
This paper describes a method which use the well known S+P and TT transforms to encode an especially important part an image, a Region Of Interest (ROI) in a lossless mode. Other parts of the image (the Background) are given lower quality levels allowing higher compression. The ROI coding is done in the framework of an embedded wavelet based image compression algorithm. All coding, regional and...
متن کاملFuzzy-Decision-based Segmentation Approach for Detecting Region of Interest
Many clustering strategies have been used, such as the hard clustering scheme and the fuzzy clustering scheme, each of which has its own special characteristics. The conventional hard clustering method restricts each point of the data set to exclusively just one cluster. As a consequence, with this approach the segmentation results are often very crisp, i.e., each pixel of the image belongs to ...
متن کاملNew approach to JPEG 2000 compliant Region Of Interest coding
Region Of Interest (ROI) coding is one of the innovative functionalities supported by JPEG 2000, the new ISO/ITU-T still image coding standard developed by the Joint Photographic Experts Group (JPEG). It enables a non-uniform distribution of the image quality between a selected region (the ROI) and the rest of the image (background). This feature is obtained by scaling background coefficients i...
متن کاملLossless Region of Interest with a Naturally P Ogressive Still Image Coding Algorithm
In this paper, an embedded wavelet based image coding algorithm is described. The algorithm allows certain regions of the image to be coded losslessly so that they can be exactly recovered by the decoder, while the remaining part is coded in a lossy manner. This maintains high compression while meeting the requirement of having lossless Regions of Interest (ROI’s) in certain applications, like ...
