Method Detail |
---|
public static FeatureDetector create(int detectorType)
Creates a feature detector by its name.
The following detector types are supported:
"FAST"
-- "FastFeatureDetector"
"STAR"
-- "StarFeatureDetector"
"SIFT"
-- "SIFT" (nonfree module)
"SURF"
-- "SURF" (nonfree module)
"ORB"
-- "ORB"
"MSER"
-- "MSER"
"GFTT"
-- "GoodFeaturesToTrackDetector"
"HARRIS"
-- "GoodFeaturesToTrackDetector" with Harris
detector enabled
"Dense"
-- "DenseFeatureDetector"
"SimpleBlob"
-- "SimpleBlobDetector"
Also a combined format is supported: feature detector adapter name
("Grid"
-- "GridAdaptedFeatureDetector", "Pyramid"
-- "PyramidAdaptedFeatureDetector") + feature detector name (see above), for
example: "GridFAST"
, "PyramidSTAR"
.
detectorType
- Feature detector type.public void detect(java.util.List<Mat> images, java.util.List<MatOfKeyPoint> keypoints)
Detects keypoints in an image (first variant) or image set (second variant).
images
- Image set.keypoints
- The detected keypoints. In the second variant of the method
keypoints[i]
is a set of keypoints detected in images[i]
.public void detect(java.util.List<Mat> images, java.util.List<MatOfKeyPoint> keypoints, java.util.List<Mat> masks)
Detects keypoints in an image (first variant) or image set (second variant).
images
- Image set.keypoints
- The detected keypoints. In the second variant of the method
keypoints[i]
is a set of keypoints detected in images[i]
.masks
- Masks for each input image specifying where to look for
keypoints (optional). masks[i]
is a mask for images[i]
.public void detect(Mat image, MatOfKeyPoint keypoints)
Detects keypoints in an image (first variant) or image set (second variant).
image
- Image.keypoints
- The detected keypoints. In the second variant of the method
keypoints[i]
is a set of keypoints detected in images[i]
.public void detect(Mat image, MatOfKeyPoint keypoints, Mat mask)
Detects keypoints in an image (first variant) or image set (second variant).
image
- Image.keypoints
- The detected keypoints. In the second variant of the method
keypoints[i]
is a set of keypoints detected in images[i]
.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.public boolean empty()
