Method Detail

sift

public static <T extends ImageGray> DetectDescribePoint<T,BrightFeature> sift(ConfigCompleteSift config)

Creates a new SIFT feature detector and describer.

Parameters:

config - Configuration for the SIFT detector and descriptor.

Returns:

SIFT

Creates a SURF descriptor. SURF descriptors are invariant to illumination, orientation, and scale. BoofCV provides two variants. Creates a variant which is designed for speed at the cost of some stability. Different descriptors are created for color and gray-scale images.

[1] Add tech report when its finished. See SURF performance web page for now.

Parameters:

configDetector - Configuration for SURF detector

configDesc - Configuration for SURF descriptor

configOrientation - Configuration for orientation

Returns:

SURF detector and descriptor

Color version of SURF stable. Features are detected in a gray scale image, but the descriptors are computed using a color image. Each band in the page adds to the descriptor length. See DetectDescribeSurfPlanar for details.

Parameters:

configDetector - Configuration for SURF detector

configDesc - Configuration for SURF descriptor

configOrientation - Configuration for orientation

Returns:

SURF detector and descriptor
