Filter

DicomImage.Filter method

Effortlessly enhance specific areas of your image by applying filters to designated rectangles. This method provides developers with precise control over image manipulation, allowing for targeted adjustments to achieve desired visual effects with ease.

public override void Filter(Rectangle rectangle, FilterOptionsBase options)
ParameterTypeDescription
rectangleRectangleThe rectangle.
optionsFilterOptionsBaseThe options.

Examples

The following example applies various types of filters to a DICOM image.

[C#]

string dir = "c:\\temp\\";

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = (Aspose.Imaging.FileFormats.Dicom.DicomImage)image;

    // Apply a median filter with a rectangle size of 5 to the entire image.
    dicomImage.Filter(dicomImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.MedianFilterOptions(5));
    dicomImage.Save(dir + "sample.MedianFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = (Aspose.Imaging.FileFormats.Dicom.DicomImage)image;

    // Apply a bilateral smoothing filter with a kernel size of 5 to the entire image.
    dicomImage.Filter(dicomImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.BilateralSmoothingFilterOptions(5));
    dicomImage.Save(dir + "sample.BilateralSmoothingFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = (Aspose.Imaging.FileFormats.Dicom.DicomImage)image;

    // Apply a Gaussian blur filter with a radius of 5 and a sigma value of 4.0 to the entire image.
    dicomImage.Filter(dicomImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.GaussianBlurFilterOptions(5, 4.0));
    dicomImage.Save(dir + "sample.GaussianBlurFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = (Aspose.Imaging.FileFormats.Dicom.DicomImage)image;

    // Apply a Gauss-Wiener filter with a radius of 5 and a smooth value of 4.0 to the entire image.
    dicomImage.Filter(dicomImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.GaussWienerFilterOptions(5, 4.0));
    dicomImage.Save(dir + "sample.GaussWienerFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = (Aspose.Imaging.FileFormats.Dicom.DicomImage)image;

    // Apply a motion wiener filter with a length of 5, a smooth value of 4.0 and an angle of 90.0 degrees to the entire image.
    dicomImage.Filter(dicomImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.MotionWienerFilterOptions(10, 1.0, 90.0));
    dicomImage.Save(dir + "sample.MotionWienerFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.dicom"))
{
    Aspose.Imaging.FileFormats.Dicom.DicomImage dicomImage = (Aspose.Imaging.FileFormats.Dicom.DicomImage)image;

    // Apply a sharpen filter with a kernel size of 5 and a sigma value of 4.0 to the entire image.
    dicomImage.Filter(dicomImage.Bounds, new Aspose.Imaging.ImageFilters.FilterOptions.SharpenFilterOptions(5, 4.0));
    dicomImage.Save(dir + "sample.SharpenFilter.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
