CarlosGS / lightweight_camera_motion.py

Last active January 9, 2022 17:15

Connect to an MJPG stream and compute the general direction of motion (like optic flow, but lighter). The script first crops and downsamples the JPG frames using the JPEGtran library, to allow processing in low power platforms like the Raspberry Pi.
