My software for
Edge Detect By Line
The software looks at detecting edges from an image, based upon the concept of lines, the idea being that a line delineates an edge.
Different images and parts of images are different. Some have very stong contrast in brightnesses and others less so, some are more delineable from their contrasting hues, some from a contrast in colour saturation. The software therefore has paramaters in the selections to the right of the colour-picker, that enable experiments to be undertaken on a given photo, to see what works best for the job in hand.
The coding scripts used by this page are all client-side Javascript. It works reasonably fast, I am optimising all the time, could be faster though because of the volume of data being handled. Pushing the processing to the server does not seem all that helpful, though as with all my software I am constantly experimenting.
