Hello everyone

I am trying to speed up performance about resize() and wrapAffine() in OpenCV 2.4.8 version.

When I use these methods for the first time,

it will auto generate .clb file (it should be OpenCL binary kernel) that takes very long time.

However, I consider it just take longer time for the first time since I already generate the kernel files.

Unfortunately when I release program to another computer, this scenario happen again.

It generate different named files. Please check below image.

Does anyone know the mechanism?

Thanks Hank

-- why invest any effort with such an outdated version ?

For backward compatible purpose,since this project has been used 2.4.8 version for a while without any issue.
