Examples with OrientationIntegral boofcv.abst.feature.orientation.OrientationIntegral used on opensource projects

Example 1 with OrientationIntegral

use of boofcv.abst.feature.orientation.OrientationIntegral in project BoofCV by lessthanoptimal.

the class FactoryPointTracker method combined_ST_SURF_KLT.

/**
 * Creates a tracker which detects Shi-Tomasi corner features, describes them with SURF, and
 * nominally tracks them using KLT.
 *
 * @see ShiTomasiCornerIntensity
 * @see DescribePointSurf
 * @see boofcv.abst.feature.tracker.DdaManagerDetectDescribePoint
 *
 * @param configExtract Configuration for extracting features
 * @param kltConfig Configuration for KLT
 * @param reactivateThreshold Tracks are reactivated after this many have been dropped.  Try 10% of maxMatches
 * @param configDescribe Configuration for SURF descriptor
 * @param configOrientation Configuration for region orientation.  If null then orientation isn't estimated
 * @param imageType      Type of image the input is.
 * @param derivType      Image derivative type.        @return SURF based tracker.
