Meziantou.FrameworkCornerDetectionMethod Enum
The corner detectors of ImageProcessingExtensions.DetectCorners.
public enum CornerDetectionMethodFields
| Name | Value | Description |
|---|---|---|
Harris | 0 | The Harris and Stephens detector (1988): the structure tensor of the gradients, smoothed by a Gaussian window, gives det(M) - k trace(M)², large where the gradients vary in every direction. |
ShiTomasi | 1 | The Shi and Tomasi detector (1994), "good features to track": the smaller eigenvalue of the same structure tensor. |
Fast | 2 | The FAST-9 segment test of Rosten and Drummond (2006): a pixel is a corner when 9 contiguous pixels of the circle of 16 around it, of radius 3, are all brighter or all darker by more than a threshold. Much faster, less stable under noise and blur. |
