description Object detection in many real applications requires the capability of detecting small objects in a system with limited resources. Convolutional neural networks (CNNs) show high performance in object detection, but they are not adequate to resource-limited environments. The combination of MobileNet V2 and SSDLite is one of the common choices in such environments, but it has a problem in detecting small objects. This paper analyzes the structure of SSDLite and proposes variations leading to small object detection improvement. The feature maps with the higher resolution are utilized more, and the base CNN is modified to have more layers in the high resolution. Experiments have been performed for the various configurations and the results show the proposed CNN, SSDLiteX, improves the detection accuracy AP of small objects by 1.5 percent points in the MS COCO data set.
