Introduction

This site dedicated to high performance computer architecture and embedded systems.
Image processing
  • Connected Component Labeling: the Light Speed Labeling is still the world fastest algorithm
  • Motion Detection algorithms: sigmadelta segmentation
  • Multi-target tracking: agile algorithmes combining mean-shift and covariance matching

Computer Architecture Benchmarking
Benchmarking COTS components with classical image processing algorithms like: Optimized implementations of image processing 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)
