Lossless Region of Interest with Embedded Wavelet Image Coding
نویسندگان
چکیده
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 full image, is done in a naturally progressive manner all the way up to lossless.

Lossless 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 ...

متن کاملAn Automatic Technique for Region- Based Coding of Medical Images
Selective compression of a medical image (MI) becomes an important task in fields of diagnosis, in solving archiving, and transmission problems. In this paper, a proposed bichannel automatic compression technique for medical image processing (MIP) with ROI is introduced using two approaches. The first approach uses two different compression schemes (lossless and lossy) for inside and outside of...

متن کاملEmbedded to Lossless Image Coding (elic)
In this paper, a novel approach for Embedded to Lossless Image Coding (ELIC) is presented. With embedded to lossless coding, lossy encodings of the image at all lower bit rates are embedded in the lossless bit stream. This algorithm uses wavelet transforms that map integers to integers with embedded coding. The coding is based on bit significance criteria in which coefficients that become signi...
