Low-light image enhancement using generative adversarial networks

Scientific Reports
In low-light environments, the amount of light captured by the camera sensor is reduced, resulting in lower image brightness. This makes it difficult to recognize or completely lose details in the image, which affects subsequent processing of low-light ...

Evaluation of Power-Assist System by Computer Simulation

Journal of Advanced Computational Intelligence and Intelligent Informatics, 2016
Powered exoskeletons have been proposed and developed in various works with the aim of compensating for motor paralysis or reducing weight, workload, or metabolic energy consumption. However, development of the power-assist system depends on the development and evaluation of real powered exoskeletons, and few studies have evaluated the performance of ...
