rectangle, box face -> mosaic, pixelate

refer to mosaic function

def mosaic(img, rect, size):
    (x1, y1, x2, y2) = rect
    w = x2 - x1
    h = y2 - y1
    i_rect = img[y1:y2, x1:x2]
    i_small = cv2.resize(i_rect, ( size, size))
    i_mos = cv2.resize(i_small, (w, h), interpolation=cv2.INTER_AREA)
    img2 = img.copy()
    img2[y1:y2, x1:x2] = i_mos
    return img2

#.... detect face
for face_dict in faces_dict:
    x1,y1 = ( int(face_dict['x1']), int(face_dict['y1']))
    x2,y2 = ( int(face_dict['x2']), int(face_dict['y2']))

    # image = anonymize_face_pixelate(image[y1:y2, x1:x2, :] , blocks=3)
    image = mosaic(image, (x1, y1, x2, y2), 10 ) 
#.... face mosaic
