摘要
提出了一种特征融合结合软判决的飞机检测方法。以区域卷积神经网络为基本框架,依次采用L2范数归一化、特征连接、尺度缩放和特征降维来融合多层特征。为了降低网络在目标高度重叠时的漏检率,引入软判决来改进传统的非极大值抑制方法。实验结果表明,所提方法能够准确快速地检测到飞机,得到检测率为94.25%、虚警率为5.5%、平均运行时间为0.16 s的实验结果。与现有的其他检测方法相比,所提方法的各项指标均得到显著提升。
Abstract
An airplane detection method is proposed based on feature fusion and soft decision, in which the region-based convolutional neural network is used as the basic framework and the L2 normalization, feature connection, scaling, and dimensionality reduction are in turn used to fuse the multi-layer features. The soft decision, which can improve the traditional non-maximum suppression method, is introduced in order to reduce the detection-omission-rate of grids in the case of significant overlap of targets. The experimental results show that the proposed method can be used to detect airplanes accurately and quickly with a detection rate of 94.25%, a false alarm rate of 5.5%, and the average running time of 0.16 s. Compared with those of the other existing detection methods, each index of the proposed method is significantly improved.
