Dense Matching,Detector-free 有监督方法 Abstract 本文提出了一种新的局部图像特征匹配方法。首先在粗粒度上建立图像特征的检测、描述和匹配,然后在精粒度别上细化亚像素级别的密集匹配,而不是依次执行图像特征检测、描述和匹配。与使用cost volume来搜索对应关系的密集方法相比,本文借鉴Transformer使用了自注意层和互注意...
This paper presents the performance analysis of various contemporary feature detector and descriptor pair for real time face tracking. These feature detectors/descriptors are mostly used in image matching applications. Some feature detectors/descriptors like STAR, FAST, BRIEF, FREAK, and ORB can also ...
code:LoFTR: Detector-Free Local Feature Matching with Transformers 1. Introduction 图像之间的局部特征匹配是许多3D计算机视觉任务的基石,包括运动结构(SfM)、同时定位和映射(SLAM)、视觉定位等。给定要匹配的两幅图像,大多数现有的匹配方法包括三个独立的阶段:特征检测、特征描述和特征匹配。在检测阶段,首先从每个图...

We present a novel method for local image feature matching. Instead of performing image feature detection, description, and matching sequentially, we propose to first establish pixel-wise dense matches at a coarse level and later refine the good matches at a fine level. In contrast to dense meth...
