Hi - I have some images which I would like to remove specks from using the PIL. I would like to be able to say that if a pixel is in a blob of less than n contiguous pixels then all pixels in that blob should be removed.
The images are 8 bit images with only 0 and 255 values. I can think of quite crude ways of doing this but I'm sure there are some smart ways of doing it - would anyone be able to point me in the right direction ? Lastly in case it matters the reason I'm doing this is that the images are scanned images of sheets of papers on which sample signatures have been placed. Typically the signatures are much smaller than the sheets of paper so I would like to 'autocrop' the images to remove the white space around the signature. At some point in the process the images having picked up small islands of pixels (dust on scanner or paper ?) which are nowhere near the signature but which are causing my autocrop efforts to go awry.
