Publication number: 20220044352Abstract: Implementations of the present disclosure provide a solution for cross-domain image translation. In this solution, a first learning network for geometric deformation from a first to a second image domain is determined based on first and second images in the first and second domains, images in the two domains having different styles and objects in the images having geometric deformation with respect to each other. Geometric deformation from the second to the first domains is performed on the second image or geometric deformation from the first to the second domains is performed on the first image, to generate an intermediate image. A second learning network for style transfer from the first to the second domains is determined based on the first and intermediate images or based on the second and intermediate images generated. Accordingly, processing accuracy of leaning networks for cross-domain image translation can be improved and complexity is lowered.Type: ApplicationFiled: September 5, 2019Publication date: February 10, 2022Inventors: Jing LIAO, Lu YUAN, Kaidi Cao

Patent number: 11128822Abstract: An “Adaptive Exposure Corrector” performs automated real-time exposure correction of individual images or image sequences of arbitrary length. “Exposure correction” is defined herein as automated adjustments or corrections to any combination of shadows, highlights, high-frequency features, and color saturation of images. The Adaptive Exposure Corrector outputs perceptually improved images based on image ISO and camera ISO capabilities in combination with camera noise characteristics via exposure corrections by a variety of noise-aware image processing functions. An initial calibration process adapts these noise aware image processing functions to noise characteristics of particular camera models and types in combination with particular camera ISO settings. More specifically, this calibration process precomputes a Noise Aware Scaling Function (NASF) and a Color Scalar Function (CSF).Type: GrantFiled: July 26, 2016Date of Patent: September 21, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Lu Yuan, Sing Bing Kang, Chintan A.

Publication number: 20200342570Abstract: In accordance with implementations of the subject matter described herein, there is proposed a solution of visual stylization of stereoscopic images. In the solution, a first feature map for a first source image and a second feature map for a second source image are extracted. The first and second source images correspond to first and second views of a stereoscopic image, respectively. A first unidirectional disparity from the first source image to the second source image is determined based on the first and second source images. First and second target images having a specified visual style are generated by processing the first and second feature maps based on the first unidirectional disparity. Through the solution, a disparity between two source images of a stereoscopic image are taken into account when performing the visual style transfer, thereby maintaining a stereoscopic effect in the stereoscopic image consisting of the target images.Type: ApplicationFiled: January 8, 2019Publication date: October 29, 2020Inventors: Lu Yuan, Gang Hua, Jing Liao, Dongdong Chen

The communication mapping indicates authorized users allowed to communicate with the first user and respective identifications allowed to be used by the authorized users. The account used by the first user in the communication is obtained to initiate the communication with the first user. The account used is obtained in response to determining that the second user is allowed to communicate with the first user using the first identification.Type: GrantFiled: October 29, 2015Date of Patent: April 9, 2019Assignee: International Business Machines CorporationInventors: Guang Qi Li, Jia Wang, Ying Ying Xu, Qiu Lu Yuan, Jia Tian Zhong
