各位看官,最近在线特征相关的研究,本文把直线特征的提取和匹配的源码贴一下,希望对大家有所帮助,在下使用 OpenCV下的LSD 提取特征,LBD进行特征描述, KNNMatch做特征描述。同时,还有特征质量的简单筛选。 #include<iostream>#include<chrono>#include<cv.h>#include<opencv2/core/core.hpp>#include<opencv2/core/uti...
比较每组照片的,MSLD and LBD recall ratios如下图: (a) shows the performances of MSLD and LBD for the image illumination changes. From image 1 to image 5, the lighting condition gets worse. The recall ratios decrease with the increment(增长) of the lighting distortion(照明畸变). (b) shows ...
其主要思想是将局部区域内具有相同梯度方向的像素进行合并,以达到直线检测的目的 下面有用到自己更改LBD的高级参数: line_descriptor::LSDDetector::LSDOptions opts; 但是编译报错: error: ‘LSDOptions’ is not a member of ‘cv::line_descriptor::LSDDetector’ 经查找:这个错误通常是由于版本不兼容引起的。可...
【摘要】基于LSD直线段检测算法可能导致直线提取碎片化的问题,提出了改进的LSD线特征检测算法,根据角度和距离对直线进行筛选,解决了直线提取碎片化问题,采用LBD(line band discriptor)描述相邻帧图像之间的线特征相似度,提高了视觉SLAM位姿优化的计算效率,在公开数据集上对LSD算法与改进后的算法进行对比实验。结果表明,改...
The Lesion Simulating Disease (LSD) genes encode a family of zinc finger proteins that play a role in programmed cell death (PCD) and other biological processes, such as plant growth and photosynthesis. In the present study, we report the reconstruction of the evolutionary history of the LSD ...
摘要: We propose a linear-time line segment detector that gives accurate results, a controlled number of false detections, and requires no parameter tuning. This algorithm is tested and compared to state-of-the-art algorithms on a wide set of natural images.关键词:...
