- Abstract:
-
Pedestrian detection methods in real scenes face some problems due to the high miss detection and false detection as well as the low detection accuracy of small size objects. To solve these problems, a pedestrian detection model based on improved SSD (PDIS) is proposed. The PDIS method improves the original SSD network model by extracting the lower-level output feature maps. It employs the abstract features of different convolutional neural network layers to detect pedestrians respectively, and then integrates the detection results of multi layers to increase the pedestrian detection performance for small sizes. Considering that the diversity of dataset can effectively enhance the generalization ability of detection algorithm, the paper expands the INRIA pedestrian dataset with complex background by collecting pedestrian images with different illumination, pose and occlusion. The PDIS method trained on expanded pedestrian dataset increases the precision rate of pedestrian detection in real scenes. The experiment results on INRIA test set indicate that the precision rate of PDIS algorithm is up to 93.8% and the miss rate is as low as 7.4%.
