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

There is a very simple way to find contours in python with scikit image. It's really just a couple line of code, like this:

    from skimage import measure
    contours = measure.find_contours(gimg, 0.8)

This returns the vector representation of the contour lines. In a separate array for each line. And it's also easy to decrease the number of points in a line by calculating an approximation. Here is a bit longer description with source code: image vectorization with python
