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)
