Preview of the output that you will get on running this code from your IDE


In this solution, we have used Skimage library

  1. Download and install VS Code on your desktop.
  2. Open VS Code and create a new file in the editor.
  3. Copy the code snippet that you want to run, using the "Copy" button or by selecting the text and using the copy command (Ctrl+C on Windows/Linux or Cmd+C on Mac).,
  4. Paste the code into your file in VS Code, and save the file with a meaningful name and the appropriate file extension for Python use (.py).file extension.
  5. To run the code, open the file in VS Code and click the "Run" button in the top menu, or use the keyboard shortcut Ctrl+Alt+N (on Windows and Linux) or Cmd+Alt+N (on Mac). The output of your code will appear in the VS Code output console.
  6. Paste the code into your file in VS Code.
  7. Save the file with a meaningful name and the appropriate file extension for Python use (.py).
  8. Install Skimage Library: Open your command prompt or terminal.
  9. Type the following command and press Enter: pip install scikit-image
  10. Add This at the start of the Code from skimage import util
  11. Add this line of code after the defines two NumPy arrays
  • Im1 = util.invert(Im1)
  • Im2 = util.invert(Im2)

13. Save and Run the Code

I hope this is useful to you. I have added the version information in the following section. I found this code snippet by searching " In skimage, how to get cmap from one generated image, and use it in another image? " in Kandi. you can try any use case.

Environment Tested

I tested this solution in the following versions. Please be aware of any changes when working with other versions.

  1. The solution is created and tested using Vscode 1.77.2 version
  2. The solution is created in Python 3.7.15 version
  3. The solution is created in Flask 2.3.3 version

This code explains how to use the skimage.util() function in Python flask. This process also facilitates an easy-to-use, hassle-free method to create a hands-on working version of code which would help how to use the skimgae.util function in Python.

                      1. What is the skimage import segmentation, and how does it work?  

                      skimage import segmentation: This module in scikit-image provides tools for image segmentation. It helps divide images into meaningful regions like intensity, color, or texture. It utilizes algorithms like watershed segmentation and region growth to achieve this.  

                      2. Who makes up the scikit-image development team?   

                      The scikit-image development team contains a collaborative community of contributors. It comprises individuals passionate about image processing. We can dedicate it to the ongoing development and improvement of the library.  

                      3. Are exclusively positive floating-point images supported by skimage? 

                      Only positive floating-point images: skimage supports only positive floating-point images. We can use it in scientific and computational applications. These images have a floating-point format with all pixel values in the positive range. It is suitable for various mathematical operations.  

                      4. How are edge modes handled in skimage?   

                      skimage handles edge modes. It provides options for how to treat pixels at the image boundaries. It supports various edge modes. Including 'constant,' 'reflect,' 'wrap,' and 'nearest,' which determine how we can extend pixel values. It also helps to know if it's interpolated when processing near the image edges.
