I want to see the EVA Feature points data, how can I save it to file?
I saw the code in evaScodeFpx.cpp it used the specific image to do the feature point after that to compare the result with specific file.
But I didn't have the image and the file, so I used my own image to do it, but when I save the result, I found that the file contents are all 0.
So how should I save this data?
