Progressive and lossless image coding using optimized nonlinear subband decompositions

In super high-de nition image applications such as medical image archival, progressive and lossless coding is required since any degradation in the decompressed image is unacceptable. Recently, nonlinear subband decompositions have received much attention as they provide very compact multiresolution representations and they allow exact reconstruction of the input image. Within this framework, w...

Lossless coding for progressive archival of multispectral images

In this paper, a nonlinear subband decomposition scheme with perfect reconstruction is proposed for lossless coding of multispectral images. The merit of this new scheme is to exploit efficiently both the spatial and the spectral redundancies contained in a multispectral image sequence. Besides, it is suitable for progressive coding, which constitutes a desirable feature for telebrowsing applic...

High-Performance Compression of Visual Information—A Tutorial Review— Part I: Still Pictures

Digital images have become an important source of information in the modern world of communication systems. In their raw form, digital images require a tremendous amount of memory. Many research efforts have been devoted to the problem of image compression in the last two decades. Two different compression categories must be distinguished: lossless and lossy. Lossless compression is achieved if...

An image multiresolution representation for lossless and lossy compression

We propose a new image multiresolution transform that is suited for both lossless (reversible) and lossy compression. The new transformation is similar to the subband decomposition, but can be computed with only integer addition and bit-shift operations. During its calculation, the number of bits required to represent the transformed image is kept small through careful scaling and truncations. ...
