LEADTOOLS provides more than 200 image processing functions in several categories, including document cleanup, medical image enhancement, color conversion and correction, noise reduction, and edge detection for .NET (C# & VB), C/C++, WinRT, iOS, macOS, Java, and Web.

This powerful collection of functions can rid scanned documents of artifacts and imperfections such as hole punches, skewed angles, borders, and dust specks. Clean black and white images improve recognition accuracy, optimize processing speed, and improve lossless compression ratios, all of which are essential to any document-imaging workflow.

You can find a small online demo that demonstrates some of these commands here:
http://demo.leadtools.co...s/DocumentCleanDemo.aspx

To find out which commands you need to use to improve the quality of your image, you can check out the Image Processing Function page that contains before and after images for each function. You can view that here:
https://www.leadtools.co...ge-processing/functions.

Here are code snippets from some of the Image Processing functions:
DeskewCommand: https://www.leadtools.co...dh/po/deskewcommand.html
Code:
// Prepare the command 
   DeskewCommand command = new DeskewCommand(); 
   //Deskew the image. 
   command.Flags = DeskewCommandFlags.DeskewImage |   DeskewCommandFlags.DoNotFillExposedArea; 
   command.Run(image); 


LineRemoveCommand: https://www.leadtools.co...o/lineremovecommand.html
Code:
 // Prepare the command 
   LineRemoveCommand command = new LineRemoveCommand();
   command.GapLength = 2; 
   command.MaximumLineWidth = 5; 
   command.MinimumLineLength = 200; 
   command.MaximumWallPercent = 10; 
   command.Wall        = 7; 
   command.Run(image); 


BorderRemoveCommand: https://www.leadtools.co...borderremovecommand.html
Code:

 // Prepare the command 
   BorderRemoveCommand command = new BorderRemoveCommand(); 
   command.Percent = 20; 
   command.Variance = 3; 
   command.WhiteNoiseLength = 9; 
   command.Run(image);
