WebDec 6, 2024 · The FLANN algorithm is suitable for the matching process with a large number of feature points. The system also optimizes the FLANN algorithm through the KNN method to achieve higher matching accuracy. Two dictionaries should be imported as parameters to determine the algorithm to be used. The first parameter is IndexParams. WebFLANN: Fast approximate nearest neighbour search algorithm for elucidating human-wildlife conflicts in forest areas.
