QR Code Detection

QR Code Detection

Detect QR codes in a still image, video or, from a camera stream.

All the outputs are loops of the same size; and the indices of each loop matches with every other output. For example, Top Left [2] and Bottom Right [2] both correspond to the same QR code at index 3.
