If executed from any location besides the repository, you must tell it where to find the bundled Haar Cascade face recognition XML file. I tried to bundle it with the binary, but it must be provided as a file to the OpenCV library, so a file path is necessary.
If you'd like to use different faces, you can provide a directory of PNG files to be imported:
chrisify --faces /path/to/faces /path/to/input.jpg > output.jpg
