Patent number: 11948278Abstract: An image quality improvement method and an image processing apparatus using the same are provided. Denoising filtering is performed to an original image by a filter to obtain a preliminary processing image. The preliminary processing image is input to a multi-stage convolutional network model to generate an optimization image through the multi-stage convolutional network model. The multi-stage convolutional network model includes multiple convolutional network sub-models, and these convolutional network sub-models respectively correspond to different network architectures.Type: GrantFiled: August 18, 2021Date of Patent: April 2, 2024Assignee: National Chengchi UniversityInventors: Yan-Tsung Peng, Sha-Wo Huang, Ming-Hao Lin, Chin-Hsien Wu, Chun-Lin Tang

Patent number: 11783454Abstract: A saliency map generation method and an image processing system using the same are provided. The method includes the following steps. An original underwater image is received. A blurring processing is performed on the original underwater image to generate a defocus map. The defocus map is input to an auxiliary convolutional network model to obtain multiple feature maps of the defocus map. The original underwater image and the feature maps are input to a main convolutional network model to generate a saliency map of the original underwater image.Type: GrantFiled: August 19, 2021Date of Patent: October 10, 2023Assignee: National Chengchi UniversityInventors: Yan-Tsung Peng, Yu-Cheng Lin

Publication number: 20230046951Abstract: A system for assessing risks of T2DM complications includes: a data acquisition module obtaining and inputting assessment parameters of a patient with T2DM into a risk assessment module; and the risk assessment module inputting the assessment parameters into a number of risk equations and using it to calculate risk values of the complication occurring after a period of time. The risk equation for all diabetic complications (i,j) is: ra(t,i,j)=1?exp{[H(t0)?H(t1)]Ca(t,i,j)} ra(t, i, j) is the risk value for the patient to develop the complication j from the current disease i at age t. t0 is an age of one patient at a state of the disease i. t1 is an age of the patient after the period of time. t is an age between t0 and t1. H(t0) and H(t1) are hazards of the complication occurring at the age t0 and the age t1, respectively.Type: ApplicationFiled: August 3, 2022Publication date: February 16, 2023Applicants: National Chengchi University, Kaohsiung Medical University, National Health Research InstitutesInventors: Ming-Yen Lin, Jia-Sin Liu, Ping-Hsun Wu, Yi-Wen Chiu, Chih-Cheng Hsu, Shang-Jyh Hwang, Hsing Luh
