Classes
- AKAZE
Wrapped AKAZE detector
- AgastFeatureDetector
Wrapped AGAST detector
- BFMatcher
Wrapped BFMatcher
- BOWImgDescriptorExtractor
Class to compute an image descriptor using the bag of visual words. Such a computation consists of the following steps:
- Compute descriptors for a given image and its key points set.
- Find the nearest visual words from the vocabulary for each key point descriptor.
- Compute the bag-of-words image descriptor as is a normalized histogram of vocabulary words encountered in the image. The i-th bin of the histogram is a frequency of i-th word of the vocabulary in the given image.
- BOWKMeansTrainer
Kmeans-based class to train visual vocabulary using the bag of visual words approach.
- Brisk
BRISK: Binary Robust Invariant Scalable Keypoints
- DescriptorMatcher
Descriptor matcher
- FastFeatureDetector
FAST(Features from Accelerated Segment Test) keypoint detector. See Detects corners using FAST algorithm by E. Rosten ("Machine learning for high-speed corner detection, 2006).
- Feature2D
The feature 2D base class
- Features2DInvoke
Library to invoke Features2D functions
- Features2DToolbox
Tools for features 2D
- FlannBasedMatcher
This matcher trains flann::Index_ on a train descriptor collection and calls its nearest search methods to find the best matches. So, this matcher may be faster when matching a large train collection than the brute force matcher.
- GFTTDetector
Wrapping class for feature detection using the goodFeaturesToTrack() function.
- KAZE
Wrapped KAZE detector
- MSER
MSER detector
- ORB
Wrapped ORB detector
- SIFT
Wrapped SIFT detector
- SimpleBlobDetector
Simple Blob detector
- SimpleBlobDetectorParams
Parameters for the simple blob detector
