| BOWImgDescriptorExtractor |
Class to compute an image descriptor using the bag of visual words. Such a computation consists of the following
steps:
1. Compute descriptors for a given image and its key points set.
2. Find the nearest visual words from the vocabulary for each key point descriptor.
3. 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.

| 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).

| 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.
