Patent number: 11449966Abstract: A computer-implemented method for increasing the image resolution of a digital image is provided. The method includes performing bicubic upsampling of the digital image to generate a base high-resolution (HR) image. The digital image is converted from a red-green-blue (RGB) color space to a Luma (Y), Chroma Blue Difference (Cb), and Chroma Red Difference (Cr) (YCbCr) color space to generate a low-resolution (LR) residual image. A plurality of convolutional layers of a neural network model is applied to the LR residual image to convert it to a plurality of HR residual sub-images corresponding to the digital image. An HR image corresponding to the digital image is generated using the base HR image and the plurality of HR residual sub-images.Type: GrantFiled: June 18, 2020Date of Patent: September 20, 2022Assignee: Huawei Technologies Co., Ltd.Inventors: Wei Su, Xin Liu, Hongyu Sun, Xiaoxing Zhu, Fan Zhang

Patent number: 11439341Abstract: A treatment efficacy of a treatment for treating a parkinsonian disease is determined. A first set of imaging information/data associated with a dMRI scan of an individual's brain captured at a first time and a second set of imaging information/data associated with a dMRI scan of the individual's brain captured at a second time are received. The individual underwent the treatment for a time period comprising at least part of the time between the first and second times. An expected change between the first and second times is determined based on a natural progression of the parkinsonian disease. The first and second sets of imaging information/data are analyzed to determine a first free-water pattern and a second free-water pattern. Based on the first and second free-water patterns, a disease progression score is determined. Based on the disease progression score and the expected change, a treatment efficacy for treating the individual with the treatment is determined.Type: GrantFiled: June 18, 2020Date of Patent: September 13, 2022Assignee: University of Florida Research Foundation, IncorporatedInventor: David E.
