Small-Target Complex-Scene Detection Method Based on Information Interworking High-Resolution Network

Abstract

The CNN (convolutional neural network)-based small target detection techniques for static complex scenes have been applied in many fields, but there are still certain technical challenges. This paper proposes a novel high-resolution small-target detection network named the IIHNet (information interworking high-resolution network) for complex scenes, which is based on information interworking processing technology. The proposed network not only can output a high-resolution presentation of a small target but can also keep the detection network simple and efficient. The key characteristic of the proposed network is that the target features are divided into three categories according to image resolution: high-resolution, medium-resolution, and low-resolution features. The basic features are extracted by convolution at the initial layer of the network. Then, convolution is carried out synchronously in the three resolution channels with information fusion in the horizontal and vertical directions of the network. At the same time, multiple utilizations and augmentations of feature information are carried out in the channel convolution direction. Experimental results show that the proposed network can achieve higher reasoning performance than the other compared networks without any compromise in terms of the detection effect.

“…Furthermore, the HDN was used to learn the contextual information of objects while the BFAM aims to resolve the network's limitation of top-down information flow (parallel connections from the last layers to the first layers) with cross-scale connections in order to improve the model efficacy. Fu et al in [122] extended the ResNet structure to ResNeXt-RC and proposed IIHNet. IIHNet is a convolution-based network based on three key concepts: (i) information fusion; (ii) information exchange between different resolutions and modules; and (iii) a multiscale network.…”
