Computer Architecture

Optimized implementations of image procesing and media algorithms:

Contours and edge detection algorithms: VLIW, Altivec & SSE2
Point of Interest: Harris & Achard algorithm for Altivec & SSE2
Optical Flow Algorithm: modified Lucas Kanade algorithm for Onera DTIM
Wavelet Transform
Scan Transform (based on Alain Merigot's idea)

Benchmark

A part of my activity is to benchmark COTS components with classical image processing algorithms like:

Contours & edges detectors: Canny, Deriche, Federico Garcia Lorca (aka FGL ;-)
Optical Flow algorithms: Horn-Shunk, Lucas-Kanade, for Onera DTIM team

Big Brother is watching you

just smile ;-)
