WebFeb 15, 2024 · FlannBasedMatcher is also used to match or search for the features of one image to another image. this function is available in the OpenCV library. It uses Nearest Neighbors Approach and usually runs faster than BruteForceMatcher for various datasets. It also works great with large datasets. WebJan 8, 2011 · Detailed Description Flann-based descriptor matcher. 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.
