Description

In my setup, I have a GTX 280M GPU (112 CUDA cores, 1Gb of memory). When I try to run gpu::FarnebackOpticalFlow or gpu::PyrLKOpticalFlow on 720x480 images and default of recommended parameters, I get:

For FarnebackOpticalFlow

/modules/gpu/src/cuda/optical_flow_farneback.cu:429: error: (-217) too many resources requested for launch in function boxFilter5Gpu

And for PyrLKOpticalFlow

/modules/gpu/src/cuda/pyrlk.cu:516: error: (-217) too many resources requested for launch in function lkSparse_caller

As a reference, I may comment that gpu::GoodFeaturesToTrackDetector_GPU and gpu::BroxOpticalFlow work well.

Could you provide values of other used parameters or simple code example for bug reproduction?

Thank you the report. It seems it is related to old GPU architectures (sm_11) which have less registers on chip.

Adding my guys to solve this.

Sure.

For FarnebackOpticalFlow, I tried this:

        gpu::GpuMat gPrv(prv);
        gpu::GpuMat gNxt(nxt);
        gpu::GpuMat gFlwX;
        gpu::GpuMat gFlwY;
        gpu::FarnebackOpticalFlow farnebackOpticalFlow;
        farnebackOpticalFlow(gPrv, gNxt, gFlwX, gFlwY);

For PyrLKOpticalFlow, this is my code:

        gpu::GpuMat gPrv(prv);
        gpu::GpuMat gNxt(nxt);
        gpu::GpuMat gFeatures;
        gpu::GoodFeaturesToTrackDetector_GPU cornerDetector = gpu::GoodFeaturesToTrackDetector_GPU(20, 0.1, 7);
        cornerDetector(gPrv, gFeatures);

        gpu::GpuMat gFlow;
        gpu::GpuMat gStatus;
        gpu::PyrLKOpticalFlow lkTracker;
        lkTracker.sparse(gPrv, gNxt, gFeatures, gFlow, gStatus);

Note that setting number of features lower than default (1000) didn't help.

My images are 720x480 color images (prv and nxt) and GPU GTX 260m (not 280m). I run Ubuntu 10.04 amd64.

Thanks.
