Provides cvloop, a way to show opencv video loops. Designed for jupyter notebooks.
Simple example: Show webcam feed.
from cvloop import cvloop
cvloop()More complex example: Show webcam feed side by side with inverted image.
from cvloop import cvloop
cvloop(function=lambda frame: 255 - frame, side_by_side=True)Complex example: Show video file with background extraction (See OpenCV Documentation; Video).
from cvloop import cvloop
import cv2
def mog2(frame):
return mog2.fgbg.apply(frame)
mog2.fgbg = cv2.createBackgroundSubtractorMOG2()
cvloop('768x576.avi', function=mog2, side_by_side=True)More examples: For more examples check out the examples notebook.
You can simply install cvloop using pip (make sure to install matplotlib, numpy, OpenCV and Jupyter):
pip install cvloop
Or, if you are using conda and don't want to worry about requirements, just use conda-forge:
conda config --add channels conda-forge conda install cvloop
