Fast computation of local correlation coefficients
Advanced Signal Processing Algorithms, Architectures, and Implementations XVIII
This paper presents an acceleration method, using both algorithmic and architectural means, for fast calculation of local correlation coefficients , which is a basic image-based information processing step for template or pattern matching, image registration, motion or change detection and estimation, compensation of changes, or compression of representations, among other information processing objectives. For real-time applications, the complexity in arithmetic operations as well as indoi:10.1117/12.796332 fatcat:qlbf5523l5akveygxmrsueupne
