Image Fusion Algorithm Based on Thermal Radiation Information Retention
Zhenlong QIAN, and Bo CHEN
Focusing on the issue that existing algorithms of infrared and visible image fusion cannot retain thermal radiation information from infrared images, an image fusion algorithm based on thermal radiation information retention was proposed. Multi-scale decomposition of infrared and visible light images was performed thro

Real-time Dynamic Blind Pixel Detection and Compensation Method for Mid-wave Infrared Camera
Chao SUN, Hongwen ZHANG, Pei WANG, and Jun LI
The existence of blind pixels significantly affects the imaging quality of infrared cameras. Scene-based methods for blind pixel detection and compensation can effectively solve such problems. This study proposes an improved local "3?" method. The average noise of the infrared image is obtained by calculating

Improved Infrared Image Edge Detection Algorithm Based on DexiNed
Qian HE, and Boyun LIU
Compared with optical image edge detection, there are fewer studies on infrared image edge detection, and most of them are based on traditional methods, such as edge detection operators and mathematical morphology. In essence, they only consider the sharp local changes of infrared images to detect edges, so they are al

Fault Diagnosis of Reliability Test for Low-Light-Level Vision Device Based on Structural Similarity Algorithm
Yongtao LI, Yalei HE, and Fengling WU
At present, fault diagnosis in direct-view low-light-level photo-optical equipment is mainly conducted by manual detection, which is inefficient, error prone (faults will often be missed), and does not create a valid record. This paper proposes an automatic diagnostic method based on machine vision. In this method, a s
