Easily pick out and save images which contain motion from a stream of images.

• Send images into the MotionSaver, and it'll save the ones with motion.
• Optionally save images from before and after motion occurs.
• Easy to configure and use.

• Python 3.5 or above
• Pillow 4+

pip install motion-saver

Continuously add a stream of images to the Motion Saver. When motion is detected it will save the previous 30 seconds of images, and keep saving until 20 seconds has passed since the last motion was detected.

from datetime import datetime

from motionsaver import MotionSaver

ms = MotionSaver()
ms.motion_threshold = 0.1
ms.save_previous_seconds = 30
ms.save_post_seconds = 20

while True:
    now = datetime.now()

    pillow_img = get_image()
    filename = '{}.jpg'.format(now.strftime('%Y%m%d-%H%M%S'))

    ms.add_image(pillow_img, now, filename)
