Object for storing corner points
This object stores information about feature points detected from a 2-D grayscale image.
plot |
Plot points |
isempty |
Determine if points object is empty |
length |
Number of stored points |
selectStrongest |
Select points with strongest metrics |
size |
Return size of points object |
selectUniform |
Select uniformly distributed subset of feature points |
gather |
Retrieve cornerPoints from the GPU |
AlthoughcornerPoints
may hold many points, it is a scalar object. Therefore,numel
(cornerPoints
) always returns1
. This value may differ fromlength
(cornerPoints
), which returns the true number of points held by the object.
