A custom made Digital Image Processor

Digital Image Processing

This is a project created by Víctor Felipe (vjfn1990@gmail.com) and Alejandro Sans (sansalejandro@gmail.com) as a project for a Digital Image Processing course (Universidad Central de Venezuela).

This project shows multiple techniques of Image Processing made on a simple application in C#

When you run this project, you will see a window with a menu:

  • File

    • Open: Browse an image and open it on the editor.
    • Reopen: Reopen the original image.
    • Save: Save the current image on chosen path.
    • Exit: Quit the editor.

  • Show

    • Info: Show the dimensions and unique colors of the current image.
    • Histogram: Show the histogram of the current image in RGB.

  • Generate

    • Grayscale: Create a grayscale of the current image.
    • Equalization: Equalize the current image.
    • Contrast: Show the histogram of the current image and allow you to modify the contrast of the RGB by choosing what pixels and position to contrast of the current image.
    • Binarize: Create a binarize image (just black and whites) of the current image.
    • Precalculus: Given a chosen path with images and the desirable dimension, create a precalculus of the images to generate a mosaic.
    • Mosaic: This button can only be activated after the precalculus was chosen. Generate a mosaic of the current image with the image chosen on the path of the precalculus.

  • Matrix of morphology: This menu section allows you to choose the filter matrix for Dilatation, Erotion, Opening, Closing on the apply section (for binarize image only).

    • Ones: Select a matrix of ones.
    • Identity: Select a matrix of identity.
    • Cross: Select a cross matrix.
    • X: Select an "x" matrix.

  • Matrix of convolution: This menu section allows you to choose the filter matrix for Apply Custom Matrix on the apply menu section for a convolution filter.

    • Custom 3x3: Open a dialog of a matrix of 3 per 3 to create for a convolution filter.
    • Custom 5x5: Open a dialog of a matrix of 5 per 5 to create for a convolution filter.
    • Custom 7x7: Open a dialog of a matrix of 7 per 7 to create for a convolution filter.

  • Apply: Apply filters on the current image.

    • Sobel: Apply Sobel filter on the current image (edge detection).
    • Roberts: Apply Roberts filter on the current image (edge detection).
    • Prewitt: Apply Prewitt filter on the current image (edge detection).
    • Average: Apply a filter calculating the average of every pixel with its surrounding.
    • Median: Apply a filter calculating the median of every pixel with its surrounding.
    • Laplace 4: Use the Laplacian 4 matrix for edge detection.
    • Laplace 8: Use the Laplacian 8 matrix for edge detection.
    • Dilatation: Only applicable on binarize image. Extend the white area of a binarize image.
    • Erosion: Only applicable on binarize image. Contract the white area of a binarize image.
    • Opening: Only applicable on binarize image. Applies an erosion followed by a dilatation.
    • Closing: Only applicable on binarize image. Applies a dilatation followed by an erosion.
    • White Top Hat: Create a grayscale image, binarize a copy of it, make an opening of the binarize image and subtract the resultant image to the grayscale image.
    • Black Top Hat: Create a grayscale image, binarize a copy of it, make a closing of the binarize image and subtract the grayscale image to the resultant image.
    • Apply Custom Matrix: Use the matrix created on menu section Matrix of convolution to filter the image.

  • Transform: Apply transformation to the image.

    • Scale: Scale the current image.
    • RotateCW: Rotate the image clock-wise.
    • RotateCCW: Rotate the image counter clock-wise.

  • Comic: CURRENTLY NOT WORKING.

Compiling

Just need to have Visual Studio 2015 and compile it!
