Aircraft detection algorithm of remote sensing image based on adaptive feature fusion and multi-scale output
In view of the problems such as missing detection and false detection of complex scene aircraft in remote sensing image by the YOLOv3 algorithm
an aircraft detection algorithm based on adaptive feature fusion and multiscale output is proposed. Firstly
K-means ++ is used to cluster the data set instead of K-means algorithm
which solves the instability of the initial clustering center of k-means. Then
on the basis of YOLOv3 network
a scale with resolution information is added
which is more conducive to the detection of small target aircraft. Finally
an adaptive feature fusion layer is added before the four scale output of the network model
which solves the problem of insufficient feature fusion at different scales and reduces or eliminates the influence of negative samples on reverse conduction. The experimental results show that the detection accuracy of the improved algorithm reaches 96.17% in the remote sensing image
which is 2.6% higher than that of the algorithm.
