Similar to EAR, MAR value goes up when the mouth opens. Now, with what we have done, the eye frames look like this: Lets try detecting and drawing blobs on those frames: The problem is that our picture isnt processed enough and the result looks like this: But we are almost there! If not for them, the program would crash if you were to blinked. Each weak classifier will output a number, 1 if it predicted the region as belonging to a face region or 0 otherwise. Also, on this stage well use another CV analysis-based trick: the eyebrows always take ~25% of the image starting from the top, so well make a cut_eyebrows function that cuts eyebrows from the eye frame, because they sometimes are detected instead of the pupil by our blob detector. The applications, outcomes, and possibilities of facial landmarks are immense and intriguing. So, download a portrait somewhere or use your own photo for that. exec(compile(f.read(), filename, 'exec'), namespace), File "C:/Users/drkbr/Desktop/Python/eye_controlled_mouse.py", line 2, in There was a problem preparing your codespace, please try again.
