public static HarrisLaplaceFeatureDetector __fromPtr__(long addr)

create

public static HarrisLaplaceFeatureDetector create(int numOctaves,
                                                  float corn_thresh,
                                                  float DOG_thresh,
                                                  int maxCorners,
                                                  int num_layers)

Creates a new implementation instance.

Parameters:

numOctaves - the number of octaves in the scale-space pyramid

corn_thresh - the threshold for the Harris cornerness measure

DOG_thresh - the threshold for the Difference-of-Gaussians scale selection

maxCorners - the maximum number of corners to consider

num_layers - the number of intermediate scales per octave

Returns:

automatically generated
