What does apply_offsets do?

[Shadow1356]

Emotion/emotions.py

Line 58 in ca64ddc

x1, x2, y1, y2 = apply_offsets(face_coordinates, emotion_offsets)

The line above applies a pre-defined offset to each detected face region before sending it through the emotion detector. When I was trying this out, it would often move the region off of the face and even cause the program to error out (and hit the try/catch). What is the reason why this is here? I'm not an expert in face detection by any means, but this seems wrong to me. Please correct me if I'm wrong.
