Use the Feature Correspondence VIs to find corners and features in images.
| Palette Object | Description |
|---|---|
| IMAQ Corner Detector |
Detects corner points in an image using the Harris or Shi-Tomasi corner detection algorithms. |
| IMAQ FAST Feature Point Detector |
Detects corners in an image using the features from accelerated segment test (FAST) algorithm. FAST identifies all interesting features in an image, and selects features so that they are consistently detected across various transformations, such as blurring, rotation, and scale. |
| IMAQ Feature Point Descriptor |
Computes feature descriptor vectors for each feature point. Supported feature descriptors are fast retina keypoint (FREAK) and binary robust invariant scalable keypoints (BRISK). |
| IMAQ Match Feature Points |
Computes correspondence between feature points. |
