Winforms app to recognize text from image

Description:

This app could recognize text (english) and digits from images and Encapsulated PostScript files.
Gives you an ability to change a threshold coefficient for better recognition.
Program has 10 recognition options (for different types of text location on image)

PLEASE INSTALL GHOSTSCRIPT FIRST

• https://github.com/ArtifexSoftware/ghostpdl-downloads/releases/download/gs9533/gs9533w64.exe
  It needs to open .eps files

Requirements to run project:

• Make sure you are on Windows now and have installed Visual Studio and .NET Framewok 4.8
• Open Tesseract WinForms.sln with Visual Studio
• and run project (F5)

How it works:

• Upload your picture (.png, .jpg)
• Or you can upload (.eps) (make sure you have installed GhostScript by link above)
• You can set the threshold coefficient that removes noizes and pixels that are not a text from picture
• Set --psm N option (mostly option number 6 works better than others). Set Tesseract to only run a subset of layout analysis and assume a certain form of image.
• The options for N are:
  • 0 = Orientation and script detection (OSD) only.
  • 1 = Automatic page segmentation with OSD.
  • 2 = Automatic page segmentation, but no OSD, or OCR.
  • 3 = Fully automatic page segmentation, but no OSD. (Default)
  • 4 = Assume a single column of text of variable sizes.
  • 5 = Assume a single uniform block of vertically aligned text.
  • 6 = Assume a single uniform block of text.
  • 7 = Treat the image as a single text line.
  • 8 = Treat the image as a single word.
  • 9 = Treat the image as a single word in a circle.
  • 10 = Treat the image as a single character.
