Bit Allocation for Spatio-temporal Wavelet Coding of Animated Semi-regular Meshes
In this paper, we propose a compression scheme for animated semi-regular meshes. This scheme includes a spatio-temporal wavelet filtering to exploit the coherence both in time and...

Tree-structure lossless coding using intervector angle
In this paper, we propose tree structure lossless coding, by which compression data are arranged in a tree structure. Current compression methods show improved performance by prod...

A Failure-Friendly Design Principle for Hash Functions
Abstract. This paper reconsiders the established Merkle-Damg˚ard design principle for iterated hash functions. The internal state size w of an iterated n-bit hash function is trea...

Opportunistic Data Structures for Range Queries
Abstract In this paper, we study the problem of supporting range sum queries on a compressed sequence of values. For a sequence of n k-bit integers, k ≤ O(log n), our data struct...

A Block Coding Method that Leads to Significantly Lower Entropy Values for the Proteins and Coding Sections of Haemophilus influ
A simple statistical block code in combination with the LZW-based compression utilities gzip and compress has been found to increase by a significant amount the level of compressi...
