Rethinking of learning-based 3D keypoints detection for large-scale point clouds registration
International Journal of Applied Earth Observation and Geoinformation, 2022 The main solution for large-scale point clouds registration is to first obtain a set of matched 3D keypoint pairs and then accomplish the point cloud registration task based on these matched keypoint pairs.

Keypoints class distribution based entropy for weighting scheme on image classification
Journal of King Saud University - Computer and Information Sciences, 2022 In bag-of-visual words (BoVW), a weighting scheme is applied to improve the discriminative power of visual words, which affect the performance of image classification. However, the weighting schemes in the BoVW model did not utilize the information class
