Running pypdfocr 0.8.2, it says:

WARNING: Could not understand output of pdfimages, please rerun with -d option and file an issue at http://github.com/virantha/pypdfocr/issues

So, here I am. The issue seems to be that the image type reported by pdfimages is "stencil" and not "image." The output of pdfimages -list file.pdf begins like so:

page   num  type   width height color comp bpc  enc interp  object ID x-ppi y-ppi size ratio

Okay, I also have this issue. I managed to figure out how to send the output I was seeing to a log so that I can actually read into what is going on. Oddly, I still had to kill the window because it wanted to keep running in some sort of loop (you can probably tell from the repeated line pypdfocr.exe: error: unrecognized arguments: --multiprocessing-fork).

Anyway. Here is the full log.
