Very sparse bitmaps are used in a wide variety of applications, ranging from adjacency matrices in representation of large sparse graphs, representation of sparse space occupancy to book-keeping in...
An Optimizing Lossy Generalization of LZW (2007)
We present a lossy generalization of Welch's LZW algorithm. We rst discuss two lossy generalizations of LZW. The two variations either try to maximise compression without worrying about image...

We present in this paper the architecture and imple-mentation of the Virtual Image Processor (VIP) which is an SIMD multiprocessor build with large FPGAs. The SIMD architecture, together with a 2D...
Binary Pseudowavelets and Applications to Bilevel Image Processing (2007)
This paper shows the existance of binary pseudowavelets, bases on the binary domain that exhibit some of the properties of wavelets, such as multiresolution reconstruction and compact support. The...
We introduce the Start/Stop codes, a generalization of (Start, Step, Stop) codes [Fiala 89]. Start/Stop codes can be otimiyed to minimize...
Searchable Compressed Representations of Very Sparse Bitmaps (Extended Abstract) (2003)
Very sparse bitmaps are used in a wide variety of applications, ranging from adjacency matrices in representation of large sparse graphs, representation of sparse space occupancy to book-keeping in...
Lossy Compression of Partially Masked Still Images (1998)
Books and magazines often contain pages containing audacious mixtures of color images and text. Our problem consists in coding the background colors of a such documents without wasting bits on...
