Hi !
Super quick post today, with a very simple scenario:
Load and image and remove the background.
To do this, I’ll use OpenCV and cvzone. Here we can see a screenshot of my office, and the removed background sample. As usual, the threshold is the important one to manage the quality.
And the sample code:
This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

| cv2.imshow('office no bg',imgNoBg) | |
| cv2.waitKey(0) | |
| cv2.destroyAllWindows() |
In next samples, I’ll show to work with this and the camera, and even replace the bacground 😀
Happy coding!
