Auto-Colour Between Edges
Two input files, an original and a converted file from my Edge Detect By Lines page. Auto-fills between the lines of the edge-detection file.
Description ↓
Auto-Colour Between Edges The colour that is filled-in is a closest match to one of the colours that has been selected on this page, matched by brightness, saturation or hue.
The match is from a row of pixels between the detected lines, for a brightness or saturation match that is on mean, median or mode average or maximum, for hue match it is on mode average.
Original image:
or image url apply
Edge detection image:
or image url apply
Use only original image (if checked will have the effect of treating every non-transparent pixel on the original as an edge)
-% done - patience! large files can take a while.
