Usage example

Edge Detector

Aspose.Imaging.License imagingLic = new License();
System.Drawing.AsposeDrawing.License drawingLic = new System.Drawing.AsposeDrawing.License();
imagingLic.SetLicense("license.lic");
drawingLic.SetLicense("license.lic");

using (var image = (RasterImage)Image.Load("polygons.cdr.png"))
{
    image.EdgeDetector(image.Bounds, EdgeDetectorType.Canny);
    image.Save("result.png");
}

Blob Detector

Aspose.Imaging.License imagingLic = new License();
System.Drawing.AsposeDrawing.License drawingLic = new System.Drawing.AsposeDrawing.License();
imagingLic.SetLicense("license.lic");
drawingLic.SetLicense("license.lic");
using (var image = (RasterImage)Image.Load("sample2.jpg"))
{
    var settings = new BlobCounterSettings
    {
        FilterBlobs = true,
        MinHeight = 10,
        MinWidth = 10,
        Order = BlobsOrder.Size
    };

    var blobs = image.DetectBlobs(settings, image.Bounds);
    var blob = blobs[0];
    using (var b = blob.GetImage(false))
    {
        b.Save("result.png");
    }
}

Corner Detector

    Aspose.Imaging.License imagingLic = new License();
    System.Drawing.AsposeDrawing.License drawingLic = new System.Drawing.AsposeDrawing.License();
    imagingLic.SetLicense("license.lic");
    drawingLic.SetLicense("license.lic");

    using (var image = (RasterImage)Image.Load("polygons.cdr.png"))
    {
        var bounds = image.Bounds;
        var points = image.CornersDetector(bounds, new MoravecCornerDetectorSettings());
        AddCornersToImage(image, points);
        image.Save("result.png");
    }

    void AddCornersToImage(RasterImage image, List<Point> points)
    {
        var graphics = new Graphics(image);
        var pen = new Pen(Color.Red, 1);
        for (var i = 0; i < points.Count; i++)
        {
            var point = points[i];
            var rect = new Rectangle(point.X - 1, point.Y - 1, 2, 2);
            graphics.DrawArc(pen, rect, 0, 360);
        }
    }

Exhaustive block matching

    using (var image = (RasterImage)Image.Load("polygons.cdr.png"))
    using (var tmp = (RasterImage)Image.Load("template.png"))
    {
        var similarity = image.ExhaustiveTemplateMatching(0.5f, tmp);
        Console.WriteLine(similarity);
    }
