Image Processing Lab in C# - The Code Project - Multimedia

Image Processing Lab is a simple tool for image processing, which includes different filters and tools to analyze images. It’s easy to develop your own filters and to integrate them with the code or to use the tools in your own application.

The following filters are implemented in the library:

  • Color filters (grayscale, sepia, invert, rotate, channel extraction, channel replacing, channel filtering, color filtering, Euclidean color filtering);
  • HSL filters (linear correction, brightness, contrast, saturation, hue modifier, HSL filtering);
  • YCbCr filters (linear correction, YCbCr filtering, channel extraction/replacement);
  • Binarization filters (threshold, threshold with carry, ordered dithering, Bayer dithering, Floyd-Steinberg, Burkes, Jarvis-Judice-Ninke, Sierra, Stevenson-Arce, Stucki dithering methods);
  • Automatic binarization (simple image statistics);
  • Mathematical morphology filters (erosion, dilatation, opening, closing, hit & miss, thinning, thickening);
  • Convolution filters (mean, blur, sharpen, edges, Gaussian);
  • 2 Source filters (merge, intersect, add, subtract, difference, move towards, morph);
  • Edge detectors (homogeneity, difference, sobel, canny);
  • Blob counter, connected components labeling;
  • Pixellate, simple skeletonization, jitter, shrink, oil painting;
  • Levels linear filter, gamma correction;
  • Median filter, adaptive smoothing, conservative smoothing;
  • Resize and rotate;
  • Texture generators based on Perlin noise;
  • Texture filters (texturer, textured filtering, textured merging);
  • Fourier transformation (lowpass and hipass filters).

You can create (save and load) your own convolution filters, or filters based on standard mathematical morphology operators. The colorized grid makes it very convenient to work with custom convolution filters.

A preview window allows you to view results of changing the filter parameters on the fly. You can scroll an image using the mouse in the preview area. All filters are applied only to a portion of the image currently viewed, to speed up preview.

A PhotoShop like histogram allows you to get information about the mean, standard deviation, median, minimum, and maximum values.

The program allows to copy to or paste from clipboard, save and print images.
