Image and video processing with Python.

Examples

Recording a video footage via webcam or other connected device.

Using the CaptureCam() object without argument will start built-in webcam and auto assign a name for the video.

>>> from capture_cam import CaptureCam
>>> session = CaptureCam()
>>> session.capture()
Press "s" to start recording.
Video will be saved to [working/directory/]Video_2019_09_03_22-49.avi

Face and Eye detection are turned off by default. Activating the eye detection will turn the face detection on automatically.

>>> from capture_cam import CaptureCam
>>> session = CaptureCam(face_detect=True, eye_detect=True)
>>> session.capture()
Press "s" to start recording.
Video will be saved to [working/directory/]Video_2019_09_03_22-49.avi

capture_cap.py can be started from command line.

python3 capture_cam.py -h
usage: capture_cam.py [-h] [-c CAM] [-4 FOURC] [-p PATH] [-f FILE] [-x RES]
                      [-r RGB] [-@ FPS] [-a FACE_DETECT] [-e EYE_DETECT]

Press "s" to start recording and "q" to close the camera. Without arguments
built-in camera will be started and a name for the video file will be auto generated.
