这段代码是使用Python中的OpenCV和Matplotlib库导入并显示一张图片。首先导入cv2和matplotlib.pyplot库,然后使用cv2.imread()函数读取图片,接着使用matplotlib.pyplot.imshow()函数显示图片,最后使用matplotlib.pyplot.show()函数展示图片。

import cv2 import matplotlib.pyplot as plt img=cv2.imread('D:/computer view/R-C.png')patch_img=img[20:150,-180:-50] cv2.imshow(patch_img)
As an AI language model, I cannot display images directly. However, I can suggest some modifications to your code to display the image using matplotlib.
Here's an updated version of your code:
```
import cv2
import matplotlib.pyplot as plt
# Read image
img = cv2.imread('D:/computer view/R-C.png')
# Extract patch
patch_img = img[20:150, -180:-50]
# Display image using matplotlib
plt.imshow(cv2.cvtColor(patch_img, cv2.COLOR_BGR2RGB))
plt.show()
```
This code will display the extracted patch using the `imshow` function of matplotlib. Note that we also need to convert the color space from BGR to RGB using the `cv2.cvtColor` function, as matplotlib expects RGB images.
import cv2 import numpy as np import matplotlib.pyplot as plt %matplotlib inline img=cv2.imread('1.jpg') cv2.imshow('image',img) cv2.waitKey(0) cv2.destroyAllWindows()
在你的代码中,imshow函数的第一个参数是窗口的名称,第二个参数是要显示的图像。你需要确保你传递了正确的图像路径和图像文件名,同时你需要确保该文件存在并且可以被打开。此外,你还需要适当地安装和配置opencv库,以确保它可以正确地运行。你可以尝试以下代码来检查是否正确安装了opencv库:
```
import cv2
print(cv2.__version__)
```
如果你的opencv库没有正确安装,那么你需要重新安装它。如果你的opencv库已经正确安装,那么你需要确保你的代码和图像文件都位于同一目录下。如果你还是遇到问题,请提供更多的代码和错误信息,我可以帮助你更好地解决问题。
