This quick tutorial explains how to remove noise from image using C#. You will get details to setting up the development environment, a list of steps, and a sample code for image denoising using C#. The given sample code performs preprocessing using the classic image denoising median filter.

Steps to Remove Noise from Photo using C#

1. Set the environment to use Aspose.OCR for .NET for noise reduction
2. Import the necessary OCR classes and enumerators
3. Apply the license for watermark-free output
4. Create an instance of the AsposeOcr engine
5. Create a preprocessing filter for removing salt-and-pepper noise using the Median filter
6. Create an instance of the OcrInput for a single image and the above-defined filter
7. Load the source input image in the OcrInput object
8. Run the OCR recognition process using the filtered input
9. Print the output recognized text to the console

These steps summarize the process for the photo noise reduction using C#. Create the PreprocessingFilter using the Median filter, link it with the OcrInput and load the input noisy image into it. Invoke the Recognize() method b passing the OcrInput to it, and print the cleaned text on the console.

Code to Remove Noise from Picture using C#

This code is a guide for image noise reduction using C#. You can use multiple denoising filters in the PreprocessingFilter, such as AutoDenoising, GaussianBlur, and Sharpen. The AutoDenoising uses a neural network and often performs Median for removing complex backgrounds.
