virtual |
Computes the descriptors for a set of keypoints detected in an image.
image | Image. |
keypoints | Input collection of keypoints. |
descriptors | Computed descriptors. Row j is the descriptor for j-th keypoint. |
stream | CUDA stream. |
|
pure virtual |
Converts keypoints array from internal representation to standard vector.
|
virtual |
Detects keypoints and computes the descriptors.
|
virtual |
Detects keypoints in an image.
image | Image. |
keypoints | The detected keypoints. |
mask | Mask specifying where to look for keypoints (optional). It must be a 8-bit integer matrix with non-zero values in the region of interest. |
stream | CUDA stream. |
