Inter-frame noise reduction method based on motion detection
Sui Xiubao,Shen Xuewei,Chen Qian,Gu Guohua,Pan Kechen,Tao Yuanrong,Kuang Xiaodong,Yu Xuelian,He Weiji,Qian Weixian +9 more
TL;DR: In this paper, the authors proposed an inter-frame noise reduction method based on motion detection, where moving targets are extracted by a multi-Gaussian mixture background model method and an overlapping stationary area between two adjacent frames are found, then interframe accumulative filtering is performed on the area, and moving target areas and non-moving target areas in non-overlapping areas are replaced by background models established by an intra-frame filtering algorithm and the multiscale mixture background models method respectively.

Chen Qian,Gao Hang,Yan Qihuan,Qian Yitao,Gu Guohua,Sui Xiubao,Yu Xuelian,Qian Weixian,He Weiji,Sun Yicheng,Pan Kechen,Liu Yuan,Tao Yuanrong,Kuang Xiaodong +13 more
TL;DR: In this article, a two-point correction infrared thermal imaging system non uniformity module introduces multi-frame weight average in scaling, thus improving scaling accuracy; the external memory is arranged for arbitration control, thus integrating scaling, correction and FLASH operation.
Patent
Blocking perception Hash tracking method with shadow removing
Sui Xiubao,Shen Xuewei,Chen Qian,Gu Guohua,Pan Kechen,Tao Yuanrong,Kuang Xiaodong,Liu Yuan,Zhao Yao,Qian Weixian,Yu Xuelian,He Weiji +11 more
TL;DR: In this article, a blocking perception hash tracking method with shadow removal is proposed, which comprises the steps of: determining shadow areas in an image according to the distribution characteristics of a shadow image in each channel grey-scale map of a CIELAB color space; then utilizing a color constancy theory to recover pixel points in the shadow areas to a non-shadow effect; combining blocking perception Hash coding values with color self-similarity for forming a similarity measure, and carrying out matching on tracked target sub-blocks of adjacent frames based on the similarity measure; and finally, combining
Patent
DDR3 arbitration controller and method applied to high-speed CCD data storage
TL;DR: In this paper, a DDR3 arbitration controller and an arbitration method applied to high-speed CCD data storage is described, where the arbitration module is responsible for arbitrating the sequence of requests, deciding a response sequence and distributing the utilization of resources of the read-write storage module when the plurality of data flows request to use the read write storage module.
