Public policies and private initiatives share the will to explore outer space and to monitor the
Earth from space sensors. Recent years have seen an increased number of space missions …

Paintings, frescoes, antique photographic prints, incunabula, old books, handwritten
documents, sculptures, ceramic fragments, and other ancient manufacts constitute the …

We consider the problem of compressing graphs of the link structure of the World Wide Web.
We provide efficient algorithms for such compression that are motivated by random graph …

We propose a new lossless and near-lossless compression algorithm for hyperspectral
images based on context-based adaptive lossless image coding (CALIC). Specifically, we …

This paper proposes an interband version of CALIC (context-based, adaptive, lossless
image codec) which represents one of the best performing, practical and general purpose …

Hyperspectral data are a challenge for data compression. Several factors make the
constraints particularly stringent and the challenge exciting. First is the size of the data: as a …

A clustered differential pulse code modulation lossless compression method for
hyperspectral images is presented. The spectra of a hyperspectral image is clustered, and …

In this letter, we propose a new algorithm for lossless compression of hyperspectral images.
The proposed method searches the previous band for a pixel of equal value to the pixel co …

We study the identity testing problem for depth 3 arithmetic circuits (∑ ∏ ∑ circuit). We give
the first deterministic polynomial time identity test for ∑ ∏ ∑ circuits with bounded top fanin …

In this chapter, we survey techniques, software tools, and applications for delta compression,
remote file synchronization, and closely related problems. We first focus on delta …
