Package boofcv.alg.feature.detdesc

Class DetectDescribeSurfPlanar<II extends ImageGray<II>>

java.lang.Object

boofcv.alg.feature.detdesc.DetectDescribeSurfPlanar<II>

Type Parameters:

II - Type of integral image

Direct Known Subclasses:

DetectDescribeSurfPlanar_MT

public class DetectDescribeSurfPlanar<II extends ImageGray<II>>
extends Object

Computes a color SURF descriptor from a Planar image. Features are detected, orientation estimated, and laplacian sign computed using a gray scale image. The gray scale image is found by computing the average across all bands for each pixel. A descriptor is computed inside band individually and stored in a descriptor which is N*length long. N = number of bands and length = number of elements in normal descriptor.
