In short, I'm looking for a tool, plug-in etc. which collects all isles of a selection up to a certain size (specified by maximum diameter or number of pixels) and subtracts them from the selection.
When dealing with a scan of a text document, the following problem often appears. Using the color or fuzzy selection tool, most of the white and lightgray background can be selected---with the exception of small isles of dirt (up to several hundreds) which have almost the same color as the characters. After inverting the selection, a tool would be very helpful which removes all isolated regions of the selection as long as they fall below a certain maximum size. As the majority of the dirt is generally smaller than the dot on the i or punctuation marks, such a method should be quite efficient. After applying it, the remaining big dirty regions may be removed from the selection, e.g., by the lasso tool. Though OCR would be in principle useful, I can't use it for my documents. If there aren't any applicable tools, I would be glad to hear about some hints for writing a .scm file. Is there any appropriate extension as a good starting point (I didn't find any)? How to write a loop for isolated regions of a selection? Is there already a function for measuring the diameter/area of a (isolated region of a) selection?
