Patent number: 10423868Abstract: Removing an embedded barcode in an image. A barcode-embedding area in an image is acquired. Pixels in the barcode-embedding area can be changed from a RGB color space to a color space with a luminance component. The luminance values of the pixels can be determined on a dark side or a light side. The luminance values of the pixels on the dark side or the light side can be mapped to luminance values falling into a whole range of a luminance interval. The pixels in the barcode-embedding area can be changed from the color space with the luminance component to the RGB color space.Type: GrantFiled: January 26, 2017Date of Patent: September 24, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Wenzhe Shi, Xiaoyu Li, Ziying Xin, Li Zhang, Wenya Zhou

Publication number: 20180122048Abstract: A method for training an algorithm to process at least a section of received visual data using a training dataset and reference dataset. The method comprises an iterative method with iterations comprising: generating a set of training data using the algorithm; comparing one or more characteristics of the training data to one or more characteristics of at least a section of the reference dataset; and modifying one or more parameters of the algorithm to optimise processed visual data based on the comparison between the characteristic of the training data and the characteristic of the reference dataset. The algorithm may output the processed visual data with the same content as the at least a section of received visual data. Some aspects and/or implementations provide for improved super-resolution of lower quality images to produce super-resolution images with improved characteristics (e.g. less blur, less undesired smoothing) compared to other super-resolution techniques.Type: ApplicationFiled: December 28, 2017Publication date: May 3, 2018Inventors: Zehan Wang, Wenzhe Shi, Ferenc Huszar, Robert David Bishop

Publication number: 20160035316Abstract: Embodiments of the present invention provide for hiding information in an image. A first pixel point and a second pixel point that are adjacent in an image are extracted. A first sub-pixel of the first pixel point and a second sub-pixel of the second pixel point that are to be combined during display on a display device are determined, wherein the display device determines a combined pixel value according to pixel values of the first sub-pixel and the second sub-pixel in a predefined manner. Information is hidden using parity properties of a sum of pixel values of the first sub-pixel and the second sub-pixel while the combined pixel value determined according to pixel values of the first sub-pixel and the second sub-pixel in the predefined manner is kept unchanged. By using unique display characteristics of a display device, information is hidden in an image without changing display effect of the image on the display device.Type: ApplicationFiled: July 16, 2015Publication date: February 4, 2016Inventors: Xiaoyu Li, Wenzhe Shi, Qian Zhang
