Vehicle Detection Algorithm of Small Target with Feature Fusion
Journal Title: 河南科技大学学报(自然科学版) - Year 2019, Vol 40, Issue 2
Abstract
In the current target detection based on deep convolution neural network, the high-dimensional features lost small-area feature information and target position information, which led to a low recognition rate for small targets. The detection method based on feature layer fusion was proposed. The high-dimensional feature map and the low-dimensional feature map were transformed into the same size through the image interpolation. Each feature map was effectively fused by setting a network self-learning parameter, so that the feature map finally detection had rich semantic information and as much target feature information as possible.Using the method, a simple convolutional neural network model was built to detect the long-distance vehicles in the road scene. The test on the KITTI dataset shows that the model's recall rates are increased by 5. 9%and 14. 6% respectively compared with the mainstream Faster-RCNN and SSD inspection framework.
