About python version of ridge detection

asked 2018-03-13 21:03:28 -0500

After installing the opencv, I try use the ridge detection function https://docs.opencv.org/3.4.1/d4/d36/...

It seems there is no attribute ximgproc in python module cv2. I try other function in the tutorial, there is not such problem.

Can you help me with that?

if you need anything from opencv_contrib, you have to build opencv libs locally, the prebuild cv2 does not have any of it.

for a build receipe, see here

I try use the example here https://docs.opencv.org/3.4.0/d4/d36/... It is really not clear to me how to use it.

Can you provide a short example on using ridge detection in python.

something like:

img = cv.imread("my.png", 0); # try grayscale first
filtered = cv.ximgproc_RidgeDetectionFilter.getRidgeFilteredImage(img)
