Soft Compression for Lossless Image Coding Based on Shape Recognition
Entropy, 2021 Soft compression is a lossless image compression method that is committed to eliminating coding redundancy and spatial redundancy simultaneously. To do so, it adopts shapes to encode an image.

Weaknesses in the HAS-V Compression Function [PDF]
, 2007 HAS-V is a cryptographic hash function which processes 1024-bit message blocks and produces a hash value of variable length. The design of the hash function is based on design principles of the MD4 family. Recently, weaknesses have been shown in members of this family. Therefore, the analysis of the HAS-V hash function is of great interest. To the best

A New Energy Function for Segmentation and Compression [PDF]
Multimedia and Expo, 2007 IEEE International Conference on, 2007 We propose a new DCT-based energy function EDCT for object-oriented segmentation and compression. By minimizing EDCT the best possible split of the image blocks can be found which leads to better segmentation and compression. Consistent motion vectors can be obtained by using an extended 3D energy function, in the spatio-temporal domain, which measures

Establishment of a Laminated Crushed Products Function and Numerical Analysis
Energies, 2019 A model of the relative compression ratio for single-particle crushed products, based on the distinct element method (DEM) and numerical analysis, was established to describe precisely the crushed products of granular particles during laminated crushing.

Multi-Functional Compression with Side Information [PDF]
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009 In this paper, we consider the problem of multifunctional compression with side information. The problem is how we can compress a source X so that the receiver is able to compute some deterministic functions f1(X, Y1), ..., fm(X, Ym), where Yi, 1 ≤ i ≤ m, are available at the receiver as side information.

Strict Avalanche Criterion of SHA-256 and Sub-Function-Removed Variants
CryptographyThe measure of diffusion, the property of dissipating patterns and statistical structures in cryptographic transformations, serves as a valuable heuristic for assessing the obscurity of patterns that could lead to collisions.
