Patent number: 11105675Abstract: This disclosure relates to monitoring of machines having one or more vibrating objects. Conventional systems that address the technical problem of detecting frequency of vibrating objects are expensive, require manual intervention, sometimes depend on prior knowledge of location of faults or involve high convergence time. Systems and methods of the present disclosure provide a cost-effective and fully automated solution that employ multiple strobe sources along with a low cost camera. Besides being cost-effective and automated, the solution also reduces convergence time significantly. Employing multiple strobe sources enables generating multiple strobing frequencies in a single iteration. The strobing frequency is a configured to be a multiple of a camera frame rate selected from a set of camera frame rates having mutually prime elements to ensure faster convergence compared to the art.Type: GrantFiled: January 23, 2020Date of Patent: August 31, 2021Assignee: Tata Consultancy Services LimitedInventors: Dibyendu Roy, Tapas Chakravarty, Arpan Pal, Archan Misra

Patent number: 11082695Abstract: A method performs entropy coding and decoding for source symbols generated in a video coding system. The method receives a palette index map for a current block, and determines a number of consecutive pixels having a same palette index as a current palette index in a scanning order through the current block. The method then converts the number of the consecutive pixels minus one to a bin string using a binarization method, and encodes the bin string using context-adaptive binary arithmetic coding (CABAC) by applying a regular CABAC mode to at least one bin of the bin string according to a context adaptively selected depending on the current palette index.Type: GrantFiled: June 18, 2019Date of Patent: August 3, 2021Assignee: HFI Innovation Inc.Inventors: Shih-Ta Hsiang, Tzu-Der Chuang

Patent number: 9363490Abstract: A method of processing a digital television (DTV) signal is disclosed. Herein, the DTV signal is generated by performing Reed-Solomon (RS) encoding on additional data, multiplexing the RS-encoded additional data with main data, RS encoding the multiplexed additional and main data, interleaving the RS-encoded additional and main data, trellis encoding the interleaved additional and main data, and transmitting a Radio Frequency (RF) DTV signal including the trellis-encoded additional and main data. The method to process the DTV signal includes receiving the DTV signal including the additional data multiplexed with the main data through an antenna, in which signaling information is periodically inserted in the additional data. The received DTV signal is demodulated including performing channel equalization on the demodulated DTV signal. Trellis decoding is performed on the channel-equalized DTV signal.Type: GrantFiled: October 24, 2011Date of Patent: June 7, 2016Assignee: LG ELECTRONICS INC.Inventors: Kyung Won Kang, In Hwan Choi

Patent number: 8634472Abstract: An image decoding method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes scaling, when a reference field has a different parity from a current field for motion compensation and when the decoded image signal is in a format in which the number of chroma pixels is vertically different from the number of luma pixels, a chroma motion vector of the chroma signal according to an accuracy for a luma motion vector of the luma signal so that a reference frame will coincide in phase of the chroma signal with a current frame. The method also includes performing motion compensation of the decoded image signal using the scaled chroma motion vector according to the accuracy of the luma motion vector of the luma signal.Type: GrantFiled: June 5, 2012Date of Patent: January 21, 2014Assignee: Sony CorporationInventors: Kazushi Sato, Osamu Sunohara, Teruhiko Suzuki, Peter Kuhn, Yoichi Yagasaki

Patent number: 8243812Abstract: A method for encoding motion-compensated video data includes generating, for a current frame, a high-pass wavelet coefficient based on a function of pixels in a temporally adjacent frame. The operations are repeated for multiple pixels in an array of pixels in the current frame to form an array of high-pass wavelet coefficients. A low-pass wavelet coefficient is generated based on a function of the high-pass wavelet coefficients. A system for coding video data includes a temporal wavelet decomposition module decomposing a pixel into a high-pass coefficient by performing a discrete wavelet transform on the pixel, a function of pixels in a previous frame, and/or a function of pixels in a subsequent frame. The system includes a motion estimation module generating motion vectors associated with the pixels in the previous frame and in the subsequent frame.Type: GrantFiled: July 15, 2009Date of Patent: August 14, 2012Assignee: Microsoft CorporationInventors: Shipeng Li, Ruiqin Xiong, Lin Luo, Jizheng Xu, Feng Wu

Patent number: 6028961Abstract: When image data is compressed in units of blocks, if a compressed data amount D obtained by reversibly compressing a block, and a predetermined value L satisfy D.ltoreq.L, the block is reversibly compressed; if they satisfy D>L, the block is irreversibly compressed, so that computer-created image data is compressed while preventing deterioration of image quality, and a gradation image or a natural image is efficiently compressed. When a pixel of interest has the same value as color data (C.sub.1) of the immediately preceding pixel, the shortest code `1` is output; when the pixel of interest has the same value as color data (C.sub.2) of a pixel, which has color data different from C.sub.1, and appears latest, the second shortest code `01` is output; when the pixel of interest has the same value as color data (C.sub.3) of a pixel, which has color data different from C.sub.1 and C.sub.2, and appears latest, the third shortest code `001` is output; when the pixel of interest has color data different from C.Type: GrantFiled: August 30, 1995Date of Patent: February 22, 2000Assignee: Canon Kabushiki KaishaInventor: Yukari Shimomura

Patent number: 5892855Abstract: An onboard forward monitoring system is disclosed in which three television cameras, each supported by a steering mechanism, take picture of a road surface located forward of a vehicle at near distance, a medium distance and a far distance zone to detect white lines which partition a lane on the road surface, thus detecting a vehicle running ahead on the lane which is defined by the white lines. To enable a reliable detection and tracking of the vehicle running ahead in any zone of the road surface even when the road is curved, the individual television cameras are steered so that a vehicle running ahead is positioned at the center of the screen whenever such vehicle is present and so that a center across the width of the lane is positioned at the center of screen when a vehicle running ahead is not detected.Type: GrantFiled: September 27, 1996Date of Patent: April 6, 1999Assignee: Aisin Seiki Kabushiki KaishaInventors: Toshiaki Kakinami, Mitsuyoshi Saiki, Kunihiko Soshi, Hisashi Satonaka
