[英]Checking pixel color in OpenCV with Python
I am currently working on a project with python and OpenCV.我目前正在使用 python 和 OpenCV 开发一个项目。 For one part of the project, I would like to check and see if one specific pixel (specifically the pixel with coordinate 100, 100) is not equal to the color black.
对于项目的一部分,我想检查一个特定的像素(特别是坐标为 100、100 的像素)是否不等于黑色。 My code is as follows.
我的代码如下。
import cv2
img = cv2.imread('/Documents/2016.jpg')
if img[100, 100] != [0, 0, 0]:
print("the pixel is not black")
When I go and fun in the terminal I get this error.当我去终端玩乐时,我收到此错误。
File "/Documents/imCam.py", line 5, in <module>
if img[100, 100] != [0, 0, 0]:
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
What am I doing wrong?我究竟做错了什么?
import cv2
image = cv2.imread('abc.jpg')
if image[50, 50, 0] != 0:
print("the pixel is not black")
Try this :)尝试这个 :)
