Parameters
- feature2DAsync
- Type: Emgu.CV.CudaIFeature2DAsync
The Feature2DAsync object - image
- Type: Emgu.CVIInputArray
The image from which the features will be detected from - keypoints
- Type: Emgu.CVIOutputArray
The result vector of keypoints - mask (Optional)
- Type: Emgu.CVIInputArray
The optional mask. - stream (Optional)
- Type: Emgu.CV.CudaStream
Use a Stream to call the function asynchronously (non-blocking) or null to call the function synchronously (blocking).
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IFeature2DAsync. When you use instance method syntax to call this method, omit the first parameter. For more information, see
