TIEVisionLibrary.createFeaturesDetector
Declaration
function createFeaturesDetector(algorithm: TIEVisionFeatureAlgorithm = ievFeatureSIFT): TIEVisionFeaturesDetector; safecall;Description
Creates a keypoint detector to find matching points in two images, e.g. to align them.ievFeatureSIFT is generally the most reliable (use a maxFeatures of 2000 or more with detect). ievFeatureORB is the fastest. See TIEVisionFeatureAlgorithm and TIEVisionFeaturesDetector for the differences between the algorithms.

Example
detector := IEVisionLib().createFeaturesDetector( ievFeatureSIFT );detector.detect( ImageEnView1.IEBitmap.GetIEVisionImage(), ImageEnView2.IEBitmap.GetIEVisionImage(), 2000 );
ImageEnView3.IEBitmap.AssignIEVisionImage( detector.getMatchingGraph() );
