Watershed Function

335 Views

Hello,

I'm trying to work with the Intel IPP Watershed Segmentation function.

I'm not sure what should I send as pMarker image.

I have an Image I want to segment using The Watershed.
I want to get back the segmented image and use the Gradient Norm as reference.

Now I calculate the image gradient norm, send it as source image and pMarker is all zero.

I want to get back segmented image but all I get is an image all zeroed.

How should I use this function?
What actually is being done in this specific image?
