Publication number: 20210302611Abstract: A computer system receives a post-stack time-domain image having a first spectrum and representing one or more subsurface structures. The computer system reconstructs an increased-frequency version of the post-stack time-domain image using L0-constrained inversion and a least-squares mismatch ratio. The increased-frequency version of the post-stack time-domain image includes structural artifacts. The computer system removes the structural artifacts from the increased-frequency version of the post-stack time-domain image using singular value decomposition. The computer system combines the increased-frequency version of the post-stack time-domain image with the post-stack time-domain image using a weighting function. The computer system generates a combined version of the increased-frequency version of the post-stack time-domain image and the post-stack time-domain image. The combined version represents the one or more subsurface structures and has a second spectrum broader than the first spectrum.Type: ApplicationFiled: March 30, 2020Publication date: September 30, 2021Inventors: Yimin Sun, Woodon Jeong, Constantinos Tsingas

Patent number: 10264965Abstract: In one aspect, disclosed herein are devices, systems, and methods for assessing human health states based on non-shadow imaging of sclera, or whites, of one or both eyes. In one aspect, the device is an on-body device. In one aspect, the system comprises a positioning aperture, an illuminating apparatus, an imaging apparatus, and/or a processing apparatus. In one aspect, the process only takes a short period of time to take images of the sclera without any operation of splicing multiple images. In one aspect, the device or system improves the quality of images by avoiding the formation of reflection of the illuminating apparatus on the images of the sclera. In a further aspect, the system can utilize the sclera images to obtain information of eye diseases and to predict the physiological and pathological changes in the health status of subject or diagnostic results, which can provide helpful information for medical diagnosis.Type: GrantFiled: December 9, 2016Date of Patent: April 23, 2019Assignee: CAPITALBIO EHEALTH SCIENCE & TECHNOLOGY (BEIJING) CO., LTD.Inventors: Guoliang Huang, Wenjun Wang, Hongmei Cao, Lili Zhang, Li Ma, Chengjin Zhang, Yimin Sun, Dong Wang, Jing Cheng
