Python edge detection and curvature calculation

Question

I know the edge detection problem has been posted before (in Java: Count the number of objects in an Image, language independent: Image edge detection), but I want to know how t

Answer 1

You can easily achieve edge detection with scipy in python.

from scipy import ndimage
edge_horizont = ndimage.sobel(greyscale, 0)
edge_vertical = ndimage.sobel(greyscale, 1)
magnitude = np.hypot(edge_horizont, edge_vertical)

And here is an example of original image and the image after edge detection.

In scikit-image, there is a special page with explanations of how to do edge detection.
