I have a large number of scans which are very similar. They are all approximately 8-1/2" x 11" in size and contain a bunch of objects which are mainly rectangular, all on a black background. Imagine several photos were placed on a scan bed, and all scanned at the same time into one big file. My job is to separate the scans out and save them with specific filenames.
I do not do the scanning myself, I am provided with the files, so doing this at the time of scanning is not an option. I need a way to work with existing scanned files.
The way I do this currently is to use the Slice tool to draw a box around each object, then double-click the Slice to give it the appropriate filiename. Then I do a "save for web" (this is for a website), which then saves all the various objects with the correct filename. I simply delete the other, miscellaneous slice files that Photoshop generates, and I now have a useable set of graphic files.
I'm wondering if there is any software or techniques in Photoshop which will save some time on the first part of this, drawing all the Slice boxes. It seems there should be some programmatic way of determining the boundaries between the black background, and inserting a bunch of slices which I can then tweak, rename, and save out of Photoshop. This would save me a lot of time, since there are nearly 1000 files of this type which I need to separate in the course of a year.
