Hello, as I was browsing through the scikit, I started to make a list of functions for which we don't have examples (neither in their docstring, nor an example script for the documentation/example gallery). I copy it here, since it seems a priority to me that we have more examples in the documentation. I was thinking of writing an example of edge detection wih canny and sobel, and completing their docstrings while I'm at this. Any other volunteer to make this list shrink :-)? Cheers, Emmanuelle ------------ feature: hog filter: median_filter, canny, sobel, prewitt, wiener graph: shortest_path, MCP morphology: * structuring elements in selem.py don't have examples in docstrings. * In grey.py, Tony added recently examples in all the docstrings -- it'd be great to have also a few examples for the gallery * label doesn't have examples transform: probabilistic_hough, homography, integral_image, integrate radon and iradon do not have examples in docstrings (but they do have a nice example in the gallery)
