Hello all,

I'm using SURF_GPU to find features on a large (40 MPx) image.

On Quatro K2000 with 2 GB of GPU RAM, it fails due to 'insufficient memory' I thought that using mask should reduce memory footprint, but it did not help. GPU memory consumption looks independent of mask size. Does anybody here have experience processing large images on GPU? What would be the best approach when performance is important?

Actually I need to process even larger images - upto several hundred MPx

Thank you

You can cut the image up into smaller tiles and the process them separately. You'll have to experiment a bit and find the right size but once you do, you can use that method to run SURF_GPU on bigger images as well
