A comprehensive evaluation of local detectors and descriptors
作者：
Highlights：
•
• First, the repeatability performance and the computational cost of each local detector are presented.
• Additionally, the efficiency and accuracy of both the real valued descriptors and binary string descriptors in terms of recall and precision are evaluated.
• Second, the visual words constructed from the real valued descriptors and binary string descriptors are evaluated for the application of large scale image search.
• Third, we calculate the accuracy and time complexity of each local detector and descriptor in the framework of fully affine space such that researchers could make a trade-off between precision and efficiency under extreme viewpoint changes.
