Properties
Methods
- Compute(InputArray, ref KeyPoint[], OutputArray)
Compute the descriptors for a set of keypoints in an image.
- Compute(IEnumerable<Mat>, ref KeyPoint[][], IEnumerable<Mat>)
Compute the descriptors for a keypoints collection detected in image collection.
- Detect(InputArray, InputArray)
Detect keypoints in an image.
- Detect(Mat, Mat?)
Detect keypoints in an image.
- Detect(IEnumerable<Mat>, IEnumerable<Mat>?)
Detect keypoints in an image set.
- DetectAndCompute(InputArray, InputArray, out KeyPoint[], OutputArray, bool)
