Hi everyone. I'm having a bit of a problem. When I try to run example code NLMeans on some larger pictures than the one provided, I get Allocating errors or uninitialized input stream error. I don't know why is this happening. Has anybody tried this? I have ATI 2600XT, driver version 8.12, ATI Stream SDK 1.3-beta. If anyone could figure out the problem I would much appreciate it.

Thanks in advance.

What is your image dimension. Maximum 2D dimensions allowed in Brook+ is 8192 x 8192. Also, make sure you have enough memory in your card that allows big images to reside on GPU memory.

If any of the case mentioned above, you can try processing your image tile-by-tile, take a look at out of core MMM example shipped with SDK.

My image dimesnions are 2272x1704. I have 256MB on my video card. I bet that if I port this code to brook that it would run fine. Also when are they gonna put back the openGL and DrectX9 backend? I'm seriously thinking of using the brook compiler instead of brook+ and AMD CAL.

Could you check error and errorLog on input streams of kernel, it can help diagnose the error (uninitialized input stream).
