Iterates to find the sub-pixel accurate location of corners, or radial saddle points

public void FindCornerSubPix( PointF[][] corners, Size win, Size zeroZone, MCvTermCriteria criteria )
Public Sub FindCornerSubPix ( _ corners As PointF()(), _ win As Size, _ zeroZone As Size, _ criteria As MCvTermCriteria _ )
public: void FindCornerSubPix( array<array<PointF>^>^ corners, Size win, Size zeroZone, MCvTermCriteria criteria )
Parameters- corners (array< array< PointF >[]()[] >[]()[])
- Coordinates of the input corners, the values will be modified by this function call
- win (Size)
- Half sizes of the search window. For example, if win=(5,5) then 5*2+1 x 5*2+1 = 11 x 11 search window is used
- zeroZone (Size)
- Half size of the dead region in the middle of the search zone over which the summation in formulae below is not done. It is used sometimes to avoid possible singularities of the autocorrelation matrix. The value of (-1,-1) indicates that there is no such size
- criteria (MCvTermCriteria)
- Criteria for termination of the iterative process of corner refinement. That is, the process of corner position refinement stops either after certain number of iteration or when a required accuracy is achieved. The criteria may specify either of or both the maximum number of iteration and the required accuracy
Return ValueRefined corner coordinates
