我当前正在使用以下代码来裁剪图像
def crop_image(image):
image = cv2.imread(image)
original_img = image.copy()
hsv_img = convert_hsv(image)
lower_blue = np.array([0, 0, 120])
upper_blue = np.array([180, 38, 255])
masked_image = mask_img(hsv_img, lower_blue, upper_blue)
result = cv2.bitwise_and(image, image, mask=masked_image)
contours = cv2.findContours(masked_image.copy(), cv2.RETR_LIST, cv2.CHAIN_APPROX_SIMPLE)
contours = imutils.grab_contours(contours)
cv2.drawContours(masked_image, contours, -1, (0, 255, 0), 3)
max_area_contour = max(contours, key=cv2.contourArea)
x, y, w, h = cv2.boundingRect(max_area_contour)
cv2.rectangle(result, (x, y), (x+w, y+h), (0, 255, 0), 3)
cont_filename = generate_contours_filename()
cv2.imwrite(cont_filename, np.hstack([image, result]))
logger.info('Successfuly saved file : %s' % cont_filename)
