detectMultiScale multi-threading c++

asked 2015-09-15 12:10:37 -0500


I have a question regarding the openCV cascade detection system (detectMultiScale). Is it possible to compile it with multithreading support? I am currently using version 2.4.8 with ROS on Ubuntu 14.04. While i m at it, I also tried using the Ocl version, which also seems to be running in a single thread.

I am grateful for any help

The detection is not optimized yet, indeed all single core processes. We need someone to pick it up and provide a parallel implementation. There is the GPU version on CUDA, but it is less performing than the detectMultiScale interface.
