Hi Nanley, I'd recommend you follow operations/common/brightness-contrast.c file for a point-filter operation (i.e. a pixel-wise filter) instead of doing what you did. Notice that in operations/common/brightness-contrast.c#n153 there's a string brightness_contrast_cl_source which is a string in opencl/brightness-contrast.cl.h, these are auto-generated files from the kernels in the opencl folder. Let me know what happens from that. Victor On Tue, Nov 18, 2014 at 4:45 PM, Nanley Chery <nanleychery@xxxxxxxxx> wrote: > Hi Victor, > > Thank you very much for taking a look.
