Progress in the research of directed thermal radiation
Zhiying Chen, Haotuo Liu, Xiaohu Wu, and Kaihua Zhang
Thermal radiation is a fundamental physical process that refers to the spontaneous emission of electromagnetic energy from objects with temperatures above absolute zero due to the thermal motion of particles. Most thermal radiators lack directionality, resulting in energy loss in unnecessary directions, which reduces t

Quadrupl-stream input-guided feature complementary visible-infrared person re-identification
Bin Ge, Nuo Xu, Chenxing Xia, and Haijun Zheng
Current visible-infrared person re-identification research focuses on extracting modal shared saliency features through the attention mechanism to minimize modal differences. However, these methods only focus on the most salient features of pedestrians, and cannot make full use of modal information. To solve this probl

No-reference light field image quality assessment based on joint spatial-angular information
Bin Wang, Yongqiang Bai, Zhongjie Zhu, Mei Yu, and Gangyi Jiang
Light field images provide users with a more comprehensive and realistic visual experience by recording information from multiple viewpoints. However, distortions introduced during the acquisition and visualization process can severely impact their visual quality. Therefore, effectively evaluating the quality of light

Dual low-light images combining color correction and structural information enhance
Shanling Lin, Yan Chen, Xue Zhang, Zhixian Lin, Jianpu Lin, Shanhong Lv, and Tailiang Guo
To enhance image quality in low-light conditions, an unsupervised dual-path low-light image enhancement algorithm is proposed, integrating color correction and structural information. The algorithm utilizes a generative adversarial network (GAN) with a generator that employs a dual-branch architecture to concurrently h

Adaptive foreground focusing for target detection in UAV aerial images
Zhenjiu Xiao, Zhengwei Wu, Jiehao Zhang, and Haicheng Qu
To address the issues of missed and false detections caused by significant scale differences of foreground targets, uneven sample spatial distribution, and high background redundancy in UAV aerial images, an adaptive foreground-focused UAV aerial image target detection algorithm is proposed. A panoramic feature refinem
