This patch is adding some code in order to extract a drawing as curves from an image. The algorithm is basically the following: - reduce the dimensions - make it gray - apply a bilateral filter in order to add some blurryness while keeping the edges - compute the histogram - guess what's the background color which should contain a large majority of the pixels - make a binary image - extract the contours in using the Suzuki algorithm - apply the Douglas-Peucker algorithm in order to reduce the number of points The algorithm is improvable but it should work pretty well if there's a clear difference between the background and the drawing. In a v2 we could use a ML model in order to improve the extraction. There's few changes related to the UI in order to make the tool usable, but they're very basic for the moment.
