set parameters similar to opencv

[jafar75]

hello sir. I want to use opencv library for cpu & cv::sift with parameters : nFeatures = 40000 octaves = 3 contrast_threshhold = 0.01 edge_threshhold = 10 sigma = 1.6

i can not find edge_threshhold in you project.

how to should I set CudaSift parameters to get results similar to above.

thanks.

The edge_threshold is hard coded. To change it go to file cudaSiftH.cu, line 163 the call to FindPointsMult, it is the 4th parameter, which btw is already 10.

The real question is how do you set sigma to 1.6...I wasn't able to understand that.

+1 did you ever get to resolve this?

Hi, Have you guys been successful to find a mapping between the cv::sift parameters and cudaSift parameters? I actually need to know what are the keypoints and descriptors from cv::sift in cudaSift.

Same question, need to know what are the keypoints and descriptors from cv::sift in cudaSift.
