Parameters
- image
- IntPtr
Input image
- corners
- array<Single,2>[,](,)[,][,]
Initial coordinates of the input corners and refined coordinates on output
- count
- Int32
Number of corners
- 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
