TLDR
A new fully scalable image coder is presented and the lossless and lossy performance of these transforms in the proposed coder are investigated, which are comparable to JPEG-LS.Abstract:
Reversible integer wavelet transforms allow both lossless and lossy decoding using a single bitstream. We present a new fully scalable image coder and investigate the lossless and lossy performance of these transforms in the proposed coder. The lossless compression performance of the presented method is comparable to JPEG-LS. The lossy performance is quite competitive with other efficient lossy compression methods.read more

Scalable Coding of Encrypted Images
TL;DR: This paper proposes a novel scheme of scalable coding for encrypted images that quantizes the subimage and the Hadamard coefficients of each data set to reduce the data amount and can be reconstructed when more bitstreams are received.

Context-based, adaptive, lossless image coding
Xiaolin Wu,Nasir Memon +1 more
TL;DR: The CALIC obtains higher lossless compression of continuous-tone images than other lossless image coding techniques in the literature and can afford a large number of modeling contexts without suffering from the context dilution problem of insufficient counting statistics as in the latter approach.
