WebSep 7, 2024 · Now, we are going to blur the part of the face. In order to do that, we need to (1) find the region of the face in the image, (2) apply blurring to that region, and (3) replace the region of the face with the blurred part. Once again, we loop over the face bounding boxes, then we use Numpy slicing to get only the part of the face from the image.
