python-CV常用方法封装

cv领域常用的图片的方法的积累与总结，使用python语言实现

def cut_img(img_path, after_path, height_start, height_stop, width_start, width_stop):
    img = cv2.imread(img_path)
    cropped_image = img[height_start:height_stop, width_start:width_stop]  # Slicing to crop the image  高：宽
    cv2.imwrite(after_path, cropped_image)
