For Windows users, IrfanView (freeware) allows
batch rotation and
cropping (to specific sizes; it doesn't do edge detection, though I
will raise a feature request). It's also useful for manual cropping,
resizing, format conversion, etc. being small and lightweight.
I'm informed that IrfanView "auto-crop borders already works, with
higher color tolerancy in: properties->editing" (I've not tried it,
yet)
