Latest Patents

Jiafeng Xiao holds a patent for a "Low light image enhancement method for online visual monitoring in metal additive manufacturing process." This invention discloses a method that captures video of the metal additive manufacturing process using a high-speed camera. The video is exported frame by frame to create a dataset of low light and bright light images. By employing Retinex vision theory, he constructed a low light image enhancement network model. This model fuses reflection and illumination maps to produce an enhanced image, while also calculating the loss function value to complete the iterative training of the network. The model is then deployed to an online monitoring hardware platform to evaluate image quality. This invention effectively overcomes the challenges posed by low light conditions, which often result in noisy images and poor geometric feature extraction accuracy.
