I wrote a simple OpenCV app in Win7 that opens an RGB image file, multiplies it pixelwise, and then saves it under a new name. I compiled OpenCV with TBB yet cannot seem to get this app to use more than one core nor get it to use more than ~40% of a single core. System idle is around 60% and it seems like I could squeeze some more speed out of OpenCV if I knew how.
Can anyone get me pointed in the right direction?
Thanks.
