Detecting objects on low-resolution (LR) images is a challenging task, as small structures and details contained in LR images are insufficient. To improve the detection accuracy on LR images, a two-stage enhancement framework is proposed in this paper. In the first stage, a lightweight image super-resolution (SR) sub-network is built by incorporating the external guidance obtained by the detection...Show More
Object detection under adverse weather conditions remains a challenging problem to date. To address this problem, a joint image and feature enhancement method called JE-YOLO is proposed. Firstly, a lightweight image enhancement network is used to enhance the low-quality image captured under adverse weather conditions. Secondly, to provide rich information for detection, two detection backbones are...Show More
Typically, image super-resolution (SR) methods are applied to the standard RGB (sRGB) images produced by the image signal processing (ISP) pipeline of digital cameras. However, due to error accumulation, low bit depth and the nonlinearity with scene radiance in sRGB images, performing SR on them is sub-optimal. To address this issue, a RAW image SR method called pyramid restoration network (PRNet)...Show More
Scene graph generation has received growing attention with the advancements in image understanding tasks such as object detection, attributes and relationship prediction, etc. However, existing datasets are biased in terms of object and relationship labels, or often come with noisy and missing annotations, which makes the development of a reliable scene graph prediction model very challenging. In ...Show More
