I've got thousands of scanned documents from various sources and they're all slightly different -- I can't count on fonts, sizes, positions (global or local), border thickness, etc. so it's not a one-mask-fits-all problem (I wish!). I've thought of detecting straight lines and removing any that are ...

I'm trying to OCR some papers which have data in a table format, but the table has borders between rows/columns and it's messing up the OCR. I think there must be some way to have ImageMagick remove the borders for me -- anyone know?

The -colorspace sRGB command does not actually convert to sRGB but from sRGB to linear RGB! That is it makes the image linear for image ...
