mouth-open's Introduction

mouth-open

Detecting when a human's mouth is open

Referenced Code

Adrian Rosebrock - drowsiness detection

I was interested in implementing a similar function for calculating the aspect ratio of the mouth instead of both eyes.

Dependencies

Python modules for:

  • scipy
  • imutils
  • numpy
  • dlib
  • cv2

Usage

This sample version uses your webcam, so make sure that the device you are using has one. Otherwise, you will need to change the code to take in a video file.

To run the code

python detect_open_mouth.py

dlib shape predictor

mouth-open's Issues

Something wrong with mouth_aspect_ratio( ) function.

As you written:
(mStart, mEnd) = (49, 68)
mouth = shape[mStart:mEnd]
A = dist.euclidean(mouth[2], mouth[9]) # 51, 59
B = dist.euclidean(mouth[4], mouth[7]) # 53, 57
C = dist.euclidean(mouth[0], mouth[6]) # 49, 55

If，mouth[0] means point 49, mouth[6] means point 55, then mouth 9 should be point 58 but not 59, mouth 7 should be 56 but not 57.
