Current performance measures are CPU based. Now we are all set to use the selfie segmentation model on our sample image first to remove or replace the background, but before that, as we know, previously we have converted the sample image to BGR format as the cv2 library read it correct in that way only, but this is not the case for media pipe library so we will re-convert the image from Edge detection, like the name implies, attempts to find the lines of contrast, or edges, in an image.
