Using GPU SURF along with OpenCV mean-shift to track a ridiculous lego car thing, in real time.

  • @AhoOo85: I used "Fast Scale Invariant Feature Detection and Matching on Programmable Graphics Hardware" by N. Cornelis and L. Van Gool

  • @AhoOo85, I did not implement GPU SURF.

  • Hi you got some nice speed going there. Did you implement the GPU-SURF ? If not , do you know where I can find it? I am doing my thesis project would be nice to try this out.

  • @trianguloGS: Correct. Not using the SURF algorithm, that is, at least on current CPUs, which have relatively few cores. SURF is very processing intensive, but it is highly parallelizable, and particularly suitable for single-instruction, multiple-data (SIMD) processors, such as GPUs (or GPGPUS). However, there are other tracking algorithms that work quite well on CPUs (e.g. mean-shift tracking using probabilistic color, Lucas-Kanade tracking using Shi and Tomasi corner detection, etc.).

  • so with a CPU it can't do tracking in real time... ¿?
