Hi everyone,
I am working on a (very) simple feature recognition task: finding
light-colored ellipses on a dark background. Has anyone seen any code/know
of any resources for feature recognition using Python?
More detail, if you want it: I am working on an algorithm that would
determine whether any given pixel represented the center of an ellipse by
determining whether it is the centroid of pixel values in a neighborhood of
a given radius. I've gotten as far as using PIL to load a .jpg,
transferring it to a NumPy matrix using tostring and fromstring -- now I
want to apply the filter. Is it possible to implement custom filters like
this in PIL? Or am I better off doing it using NumPy?
Thanks in advance for any help --
Alex
