Hello, Stephan,
I'm using SIFT plugin.
I've got a question concerning about the SIFT plugin.
Actually I'm working on Fracture images and my main goal is to detect
fracture in bone.
My problem is that the points found don't correspond exactly to what I
want, which is : edges and where there's high changes in gradients.
I've changed the "MAX_CURVATURE" in FloatArray2DScaleOctaveDoGDetector.java.
I increased from 10 to 100. It works better but not perfect.
Do you have any idea how to better detect those edge points as well?
cheers, Xin
