  Abstract

Obtaining potential gains from object detection in practical systems hinges on sufficient levels of image resolution. In this paper, a two-step guideline using deep neural network (DNN)-based super-resolution (SR) model for object detection is presented under the assumption that the DNN model takes multiple low-resolution images captured form the same scene. In the first step, enhanced deep residual networks for single image super-resolution (EDSR) is exploited to recover an intermediate high-resolution image. The second step is to perform face and object detection based on RetinaFace and EfficientDet-D7. By capturing different training and test image formats, the resulting design employs a transfer learning method with pre-trained EDSR to further leverage detection performance. We adopt three degradation models for performance analysis and provide a practical guideline for DNN-based SR reconstruction. Numerical results show the effectiveness of the proposed method in improving small-sized object detection performance.
