摘要:

提出了一种快速稳健的自适应非线性尺度特征检测子(fast robust adaptive nonlinear scale feature detector, FRANSFD),通过非线性尺度空间快速求解去除了噪声同时保证了边缘细节,并将自适应选取尺度空间组数、基于加速段检验的自适应通用角点检测子(adaptive and generic corner detection based on the accelerated segment test,AGAST)与框状拉普拉斯滤波器去除边缘响应相结合,兼顾了检测的准确性与实时性。通过与尺度不变特征转换(scale invariant feature transform,SIFT)检测子、快速鲁棒性特征(speeded up robust features,SURF)检测子、风式特征(KAZE)检测子以及二进制鲁棒性尺度不变的特征(binary robust invariant scalable keypoints,BRISK)检测子的实验对比可知,FRANSFD的5种变换鲁棒性均较强,同时速度也更快。综合性能较KAZE提高约5.76%,速度提高约47%。

Abstract:

A fast robust adaptive nonlinear scale feature detector (FRANSFD) is proposed. Noise is wiped off and edge response is guaranteed through the fast solving of the nonlinear scale space. Adaptive selection of the number of scale space and the adaptive and generic corner detection based on the accelerated segment test (AGAST), combined with frame Laplace filter via removing edge response take account of the detection accuracy and real-time performance. Compared with to feature detectors of scale invariant feature transform (SIFT), speeded up robust features (SURF), KAZE, and binary robust invariant scalable keypoints (BRISK) experiments, the FRANSFD reveals stronger robustness with five kinds of changes, and its registration speed is faster. Compared with KAZE, comprehensive robustness is increased about 5.76%, and the speed is increased about  47%.
