A console application in F# to solve a sudoku puzzle from the 9x9 grid image. Uses Emgu (OpenCV).

Download the dependencies

1. Install the x64 Cuda version of Emgu 3.2 : https://sourceforge.net/projects/emgucv/files/emgucv/3.2/libemgucv-windesktop_x64-cuda-3.2.0.2682.exe/download
2. Download the english trained data file for Tesseract OCR 4 : https://github.com/tesseract-ocr/tessdata/blob/master/eng.traineddata

Build and Test

Visual Studio 2017 solution

1. The project SudokuFromImage needs a reference to Emgu.CV.World.dll (to be found in the Emgu installation directory).
2. The project SudokuSolver needs a reference to ExtCore (a NuGet package).
3. The project SolveSudoku builds the console application ssud.exe.
4. The project Tests builds a test of 16 grid images.

In order to successfully run the tests or ssud.exe, you need to :

• Copy the x64 folder from the Emgu installation in the executable folder.
• Create a tessdata folder containing the eng.traineddata file in the executable folder.
