1. Introduction
This document contains a
comprehensive benchmark of the performance of Anona Labs IPT compared to
Matlab’s Image Processing Toolbox. More than 80% of the IPT functions where
benchmarked.
2. Benchmarking Method
2.1. System Specification:
CPU: Intel® Core2 Quad
Q6600 (2.4Ghz). Memory: 2GB RAM, DDR2 800Mhz.
Software: Windows XP,
Matlab® 7.5 (2007b), Anona Labs IPT 1.0.
2.2. Method
· Both Matlab and the IPT are set to use all processors cores (4 threads).
· Time is measured using Matlab’s ‘tic’ and ‘toc’.
· In order to eliminate overhead times related to m-files and dlls loading
each of the functions is called twice before the time measurement start.
3. Results
