on from this group. I have millions of pages of scanned
documents with each page in and individual .JPG file.
When the documents were scanned the people that did
the scanning put a colored (hot pink) separator page
between the individual documents. I was wondering if
there was any way to utilize PIL to scan through the
individual files, look at some small section on the
page, and determine if it is a separator page by
somehow comparing the color to the separator page
color? I realize that this would be some sort of
percentage match where 100% would be a perfect match
and any number lower would indicate that it was less
likely that it was a coverpage.
Thanks in advance for any thoughts or advice.
Close enough to the hue you want (and you could include saturation and intensity too, if you felt like it) across several areas of the page would be a hit for a separator.

Steve
