I highly recommend you deal with the segmentation models. You will have five different models (SINet, MODNet, MediaPipe, Selfie Segmentation, and Robust Video Matting). They are the models which perform the removal of the background. It is better to select Robust Video Matting for better accuracy of background removal. If this module is not available, go for MediaPipe or SINet. Finally hit the close button.
