Patent number: 9970810Abstract: A weighing system and a weighing method are disclosed having uninterrupted weighing functions. A plurality of load cells in the weighing system are arranged so that each load cell has a local small neighborhood, the local small neighborhood being defined by four neighboring points in front, back, left, and right of the load cell and four points on diagonal directions in a matrix. A weighing control module polls the load cells to determine whether there is failed load cell(s), and performs a calculation: W.=f(W1,W2,W3,W4,W5,W6,W7), where f is a non-linear mapping; and W1 . . . W8 represents weighing outputs of load cells corresponding to the eight points in the local small neighborhood so as to calculate an estimated weighing output of the failed load cell.Type: GrantFiled: June 3, 2015Date of Patent: May 15, 2018Assignees: METTLER TOLEDO (CHANGZHOU) PRECISION INSTRUMENT LTD., METTLER TOLEDO (CHANGZHOU) SCALE & SYSTEM LTD.Inventors: Guojun Xie, Zijian Zhu, Qi Wan

Patent number: 9754356Abstract: In various embodiments of the present disclosure, there is provided a method for processing an input image. The method includes generating a base layer portion and a detail layer portion from the input image by carrying out a linear transformation of pixels of a guidance image, and determining, for each of the pixels of the guidance image, a variance of the pixels in a surrounding window of pixels. Further, the method includes determining, for each of the pixels of the guidance image, a weight value of the pixels based on the determined variance, wherein the pixels are weighted in the linear transformation according to the determined weight value. Accordingly, a system for processing an input image is also provided.Type: GrantFiled: April 11, 2014Date of Patent: September 5, 2017Assignee: Agency for Science, Technology and ResearchInventors: Zhengguo Li, Jinghong Zheng, Zijian Zhu, Shiqian Wu, Wei Yao, Susanto Rahardja

Patent number: 9305372Abstract: Embodiments provide a method for processing a first image based on a second image, wherein each pixel in the first image has a plurality of color components and has a corresponding pixel in the second image, and wherein each value of a color component in the first image corresponds to a value of a color component in the second image. The method may include deciding, for each color component of a pixel in the first image, whether to modify the value of the color component dependent on a predetermined criterion. The method may further include determining a similarity index between the pixel in the first image and the corresponding pixel in the second image based on, for each color component of the pixel, the value of the color component of the pixel, or if it is decided that the value of the color component of the pixel is to be modified, the corresponding value of the color component in the second image.Type: GrantFiled: July 26, 2011Date of Patent: April 5, 2016Assignee: Agency for Science, Technology and ResearchInventors: Zhengguo Li, Zijian Zhu, Shiqian Wu, Shoulie Xie, Susanto Rahardja
