Witrynaproposed Oriented FAST and Rotated BRIEF (ORB) as another efficient alternative for SIFT and SURF [10]. Any of these feature detection methods can also be employed in remote sensing application such as sea ice applications, e.g. Zehen Lieu et al. used the SIFT algorithm based matching to find the icebergs whose shapes has changed due … WitrynaOriented FAST and Rotated BRIEF ( ORB) was developed at OpenCV labs by Ethan Rublee, Vincent Rabaud, Kurt Konolige, and Gary R. Bradski in 2011, as an efficient and viable alternative to SIFT and SURF. ORB was conceived mainly because SIFT and SURF are patented algorithms. ORB, however, is free to use.
WitrynaORB基本上是FAST关键点检测器和Brief描述符的融合，具有许多修改以增强性能。 首先，它使用FAST查找关键点，然后应用Harris角点测量来查找其中的前N个点。 它还使用金字塔来生成多尺度特征。 但有一个问题是，FAST不计算方向。 那么旋转不变性呢？ 作者提出了以下修改。 它计算贴片的强度加权质心，位于中心的角落。 从该角点到质心 …
