lossless compressionS+P transform proposed by Amir Said is a multiresolution representation method. It can map integers to integers, so it has been used in lossless compression of images with better performance than that of JPEG standard based on linear prediction. To further improve compression ...
the compression ratio is improved by discarding part of the color density information. The common option is 4:2:0. After this step, the information represented by 8 numbers was originally required, but now only 2 are needed, and 75% of the Cb Cr information is directly discarded. However, ...
medical imagespredictionDue to the rapidly increasing requirements for data transmission and storage, applications for fast and efficient compression of data have a very important role. Lossless compression must be applied when data acquisition is expensive. For example, lossless image compression must be...
Compressed medical images must preserve all the original data details when they are restored for image presentation. That is, medical image compression and decompression must be lossless. Data compression is a long-history technique of human activities. Abbreviation and other devices for shortening the...
Lossless image compression for few-colored imagesArchitecture that utilizes characteristics of high spatial redundancy and few colors in few-colored images to compress the image data in a hierarchical manner, and store block level information. The entire image is decomposed into fixed-size blocks, and...
This paper sheds light on the least-square (LS)-based adaptive prediction schemes for lossless compression of natural images. Our analysis shows that the superiority of the LS-based adaptation is due to its edge-directed property, which enables the predictor to adapt reasonably well from smooth ...
The explosion of digital photos has posed a significant challenge to photo storage and transmission for both personal devices and cloud platforms. In this paper, we propose a novel lossless compression method to further reduce the size of a set of JPEG coded correlated images without any loss of...
