Description

I tried the new OpenCV 3.0 RC1 for object detection. However the results were disappointing. I wrote the same code (with required changes) and compiled and ran on the same video and achieved the following results:
OpenCV2.4: 20 Seconds
OpenCV 3.0 RC1: 40 Seconds
It means 100% reduce in speed!

could you please specify:

1. CPU
2. GPU
3. OS
4. compiler
5. the output from cmake if you build OpenCV from source code
6. the output from opencv_test_core (in the beginning it should print all the information about your OpenCL configuration)
