BinarizeBradley
TiffImage.BinarizeBradley method
Binarization of an image using Bradley’s adaptive thresholding algorithm using the integral image thresholding
public override void BinarizeBradley(double brightnessDifference, int windowSize)
Parameter | Type | Description |
---|---|---|
brightnessDifference | Double | The brightness difference between pixel and the average of an s x s window of pixels centered around this pixel. |
windowSize | Int32 | The size of s x s window of pixels centered around this pixel |
Examples
The following example binarizes a TIFF image with Bradley’s adaptive thresholding algorithm with the specified window size. Binarized images contain only 2 colors - black and white.
[C#]
string dir = "c:\\temp\\";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.tif"))
{
Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)image;
// Binarize the image with a brightness difference of 5. The brightness is a difference between a pixel and the average of an 10 x 10 window of pixels centered around this pixel.
tiffImage.BinarizeBradley(5, 10);
tiffImage.Save(dir + "sample.BinarizeBradley5_10x10.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
