| Parameter | Description |
|---|---|
| I | Input grayscale or RGB image. |
| Parameter | Description |
|---|---|
| points | Structure with Location, Metric and Count fields. |
detectHarrisFeatures computes a Harris corner metric, keeps local maxima, sorts them by metric strength, and returns their image coordinates. Supported options are MinQuality, FilterSize, SensitivityFactor and ROI.
