说明：  用matlab写的印刷体数字识别程序，对matlab 6.0以上有效(Written with matlab print digital identification procedures, more effective on matlab 6.0)

粗糙集理论是一种基于对现实世界进行不确定描述的理论,属性约简是粗糙集理论的核心理论之一。对粗糙集理论进行阐述,并给出基于启发式的知识约简算法,最后结合MATLAB程序实例说明了该算法的可行性与有效性。(Rough set theory is based on the uncertainty of the real world is described in theory, attribute reduction is the core theory of rough set theory one. Elaborate on the rough set theory, and gives the knowledge-based heuristic reduction algorithm, and finally with MATLAB program example illustrates the feasibility and effectiveness of the algorithm.)

球赛门票的售票处规定每位购票者限购一张门票，且每张门票售价 50元。购票者中有 m位手持50元钱币，另有n人手持100元。假设售票处开始售票时无零钱。问这m+n人有 几种排队方式可使售票处不致出现找不出钱的局面。(The box office ticket sales are limited to the provisions of each ticket purchase a ticket, and the price of 50 yuan per ticket. Ticket-holders have m-bit hand-held 50 coins, and another n armed with 100 yuan. Suppose no small change when the ticket office began selling tickets. M+ n asking a few people queuing up outside ticket office can not find the money to avoid a situation.)

基于三个模型的自适应目标跟踪算法，中心角速度实施估计.偏移角速度固定。自带轨迹。(Three models based on adaptive tracking algorithm, the central angular velocity of the implementation of estimates. Offsets the fixed angular velocity. Own trajectory.)

为了弥补传统中值滤波器在进行图像降噪处理中的不足,在图像降噪技术中应用了自适应中值滤波器。文中重点介绍了自适应中值滤波器的工作原理并在Matlab平台上进行了仿真试验，与传统中值滤波器进行了比较,计算机仿真结果表明在对密度较大的椒盐噪声进行滤波时,自适应中值滤波较传统中值滤波具有较大的优越性。(To remedy disadvantage of traditional median filtering algorithms in image denoise ,adaptive median filter is introduced and applied to image denoise. Key technology in actual uses is analyzed and is implemented in Matlab platform.Compared with traditional median filter , the computer simulation results show that when used to filter image with the higher level of noise , adaptive median filter is preferable to traditional median filter.)
