C# Класс Accord.Imaging.Filters.Threshold

Threshold binarization.

The filter does image binarization using specified threshold value. All pixels with intensities equal or higher than threshold value are converted to white pixels. All other pixels with intensities below threshold value are converted to black pixels.

The filter accepts 8 and 16 bpp grayscale images for processing.

Since the filter can be applied as to 8 bpp and to 16 bpp images, the ThresholdValue value should be set appropriately to the pixel format. In the case of 8 bpp images the threshold value is in the [0, 255] range, but in the case of 16 bpp images the threshold value is in the [0, 65535] range.

Sample usage:

// create filter Threshold filter = new Threshold( 100 ); // apply the filter filter.ApplyInPlace( image );
