[英]**Save Image with added mask in python**
我正在尝试保存我在所有感兴趣区域上添加了白色遮罩的图像。 但出于某种原因,它没有保存最终图像,也没有返回任何错误消息。 如何保存带蒙版的图像?
import cv2
import numpy as np
image = cv2.imread('C:/Users/Desktop/testim.png')
gray_scale = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
# Set threshold level
Dark = 10
coords = np.column_stack(np.where(gray_scale < Dark))
print("xy:\n", coords)
mask = gray_scale < Dark
# Color the pixels in the mask
image[mask] = (255, 255, 255)
cv2.imshow('mask', image)
cv2.waitKey()
#save new image with the added mask to directory
if not cv2.imwrite(r'./mask.png', image):
raise Exception("Could not write image")
我认为这与程序中的几个错别字有关。 修复它们后,一切都很好。
import cv2
import numpy as np
image = cv2.imread('/content/test.png')
gray_scale = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
# Set threshold level
Dark = 10
coords = np.column_stack(np.where(gray_scale < Dark))
# print("xy:\n", coords)
mask = gray_scale < Dark
# Color the pixels in the mask
image[mask] = (255, 255, 255)
# cv2.imshow('mask', image)
cv2.waitKey()
if not cv2.imwrite(r'./mask.png', image):
raise Exception("Could not write image")
