Patent number: 9406105Abstract: In a computer-based graphics imaging system, binocular tone mapping is employed with an optimization-based framework to generate a binocular single vision image with more visual richness than a single tone-mapped image, the binocular tone mapping being guided by a binocular viewing comfort predictor (BVCP) metric in order to assure stable formation of binocularly tone-mapped image pairs, so that visual information content of the image pair can be maximized without triggering visual discomfort.Type: GrantFiled: July 30, 2013Date of Patent: August 2, 2016Assignee: The Chinese University of Hong KongInventors: Tien-Tsin Wong, Pheng-Ann Heng, Xuan Yang, Linling Zhang

Patent number: 8768001Abstract: The disclosure relates to apparatus and methods for processing images. The method for generating a manga-style image from an input image comprises: generating a line drawing from the input image; generating a manga-style screening from an input image; and overlaying the line drawing and the manga-style screening to generate the manga-style image. The method can provide a high efficient way for auto-generating manga images.Type: GrantFiled: December 10, 2010Date of Patent: July 1, 2014Assignee: The Chinese University of Hong KongInventors: Tien-Tsin Wong, Yingge Qu, Wai-Man Pang, Pheng-Ann Heng

Patent number: 8457348Abstract: Provided are methods and devices for producing an ASCII picture from a vector outline image. The method comprises rasterizing the vector outline image into a plurality of grid cells, at least one of which has a reference image; matching each reference image with an ASCII character based on log-polar histograms thereof; and gathering all matched ASCII characters to form the ASCII picture.Type: GrantFiled: June 28, 2010Date of Patent: June 4, 2013Assignee: The Chinese University of Hong KongInventors: Tien-Tsin Wong, Xuemiao Xu, Linling Zhang

Patent number: 7715657Abstract: Systems and methods for perceptual image preview are described. In one aspect, a naïve preview image is generated by downsampling a larger image. Perceptual features of the larger image are then detected. Information associated with the detected perceptual features is then incorporated into the naïve preview image to create a perceptual preview image. Since the perceptual preview image incorporates information associated with the detected perceptual features, a viewer of the perceptual preview image will be more likely to detect the presence or absence of such perceptual features in the larger image.Type: GrantFiled: February 17, 2006Date of Patent: May 11, 2010Assignee: Microsoft CorporationInventors: Zhouchen Lin, Liang Wan, Wei Feng, Tien-Tsin Wong, Zhi-Qiang Liu

Patent number: 7184041Abstract: A computer-based method and system for interactive volume rendering of a large volume data on a conventional personal computer using hardware-accelerated block filtration optimizing uses 3D-textured axis-aligned slices and block filtration. Fragment processing in a rendering pipeline is lessened by passing fragments to various processors selectively in blocks of voxels based on a filtering process operative on slices. The process involves generating a corresponding image texture and performing two-pass rendering, namely a virtual rendering pass and a main rendering pass. Block filtration is divided into static block filtration and dynamic block filtration. The static block filtration locates any view-independent unused signal being passed to a rasterization pipeline. The dynamic block filtration determines any view-dependent unused block generated due to occlusion. Block filtration processes utilize the vertex shader and pixel shader of a GPU in conventional personal computer graphics hardware.Type: GrantFiled: October 22, 2004Date of Patent: February 27, 2007Assignee: The Chinese University of Hong KongInventors: Pheng-Ann Heng, Yongming Xie, Tien-Tsin Wong, Yim-Pan Chui
