WebBinary descriptors are fast but less precise in terms of localization. They are not suitable for classification tasks. The extractFeatures function returns a binaryFeatures object. This object enables the Hamming-distance-based matching metric used in the matchFeatures function. Use Local Features WebSep 13, 2016 · Descriptor matching on the GPU. Our tests compare the use of our binary descriptors with existing floating point representations. In all cases, we used the GPU to compute the descriptor distances. Because CLATCH is a binary representation, Hamming distance is used to compute similarity of CLATCH descriptors.
