Abstract:

Aiming at the high missed detection rate and low accuracy of the current deep learning small target detection algorithm in practical applications, this paper proposes a feature fusion small target detection algorithm based on the human eye view-point map. Based on the single shot multibox detection (SSD) algorithm, through the convolution fusion of holes with different expansion rates, a shallow feature layer similar to the receptive field of the human eye is obtained on the basic network. The feature layer in the additional network performs information fusion, merges context information, adds position information and global semantic information, thereby improving the accuracy of small target detection. Validated by PASCAL VOC 2007 data set, the results show that the detection accuracy of this algorithm is improved by 3.7% compared with the traditional SSD algorithm, and the accuracy of the improved small target detection algorithm Bi-SSD is increased by 0.8%. It is verified that selecting a feature layer with more characterization ability is an effective method to improve the accuracy of small target detection.

Key words: small target detection, single shot multibox detection (SSD) algorithm, hollow convolutional spatial pyramid, feature pyramid fusion
