Parameters ()  
Public Attributes  
float  support_size 
This defines the area 'covered' by an interest point (in meters) More...  
int  max_no_of_interest_points 
The maximum number of interest points that will be returned. More...  
float  min_distance_between_interest_points 
Minimum distance between maximas (this is a factor for support_size, i.e. More...  
float  optimal_distance_to_high_surface_change 
The distance we want keep between keypoints and areas of high surface change (this is a factor for support_size, i.e., the distance is optimal_distance_to_high_surface_change*support_size) More...  
float  min_interest_value 
The minimum value to consider a point as an interest point. More...  
float  min_surface_change_score 
The minimum value of the surface change score to consider a point. More...  
int  optimal_range_image_patch_size 
The size (in pixels) of the image patches from which the interest value should be computed. More...  
float  distance_for_additional_points 
All points in this distance to a found maximum, that are above min_interest_value are also added as interest points (this is a factor for support_size, i.e. More...  
bool  add_points_on_straight_edges 
If this is set to true, there will also be interest points on straight edges, e.g., just indicating an area of high surface change. More...  
bool  do_non_maximum_suppression 
If this is set to false there will be much more points (can be used to spread points over the whole scene (combined with a low min_interest_value)) More...  
bool  no_of_polynomial_approximations_per_point 
If this is >0, the exact position of the interest point is determined using bivariate polynomial approximations of the interest values of the area. More...  
int  max_no_of_threads 
The maximum number of threads this code is allowed to use with OPNEMP. More...  
bool  use_recursive_scale_reduction 
Try to decrease runtime by extracting interest points at lower reolution in areas that contain enough points, i.e., have lower range. More...  
bool  calculate_sparse_interest_image 
Use some heuristics to decide which areas of the interest image can be left out to improve the runtime. More...
