Vidicon collect simulate image in period of time and send to computer or DSP chip through video collection card digitlization,use computer to gain eyewinker and process digital image processing:using image area segment and boder measure to calculate area and perimeter;using image smoothness to wipp offthe infection of yawp;using dynamic background and image suited technology to overcome the infection of ray;calculation the parameter of eyewinker(area, perimeter,round measurement, proportion characer and invariant monent),using least norm to design the linearity classify parts,using image matching technologyto classify eyewinker,and to judge whether the eyewinker is harmful to diff background,if the eyewinker satisfy the character require of harmful object ,system will auto-stsrt alarm device. If there ia not have found any eyewinker, Vidicon will collect new simulate image and make processing.

本设计是将摄像机或高频头采集到的模拟图像经过视频采集卡数字化后送入计算机或DSP芯片，利用计算机对采集到的一定时间段内的图像进行异物获取，并对异物图像进行数字图像处理：利用图像区域分割和边缘检测以便进行面积和周长的计算，利用图像平滑去除噪声的影响，利用动态背景运动检测法和图像配准技术克服光线的影响，并通过异物的各类参数（如面积、周长、圆形度、比例特征和不变矩等）的计算，采用最小范数分类法设计了线性分类器，利用图像匹配技术对异物进行分类，从而判断异物是否有害，针对于不同的背景，若异物满足有害物体的特征要求，则认为物体有害，自动启动报警装置，如果没有发现有害异物则新摄入的图像将取代前一时间段的图像再进行图像处理。

Among many implement schemes of decoding, the one using chips is the fastest one. Specific decoding chips like FPGA or ASIC have parallel processing structures, which make them be much fit for being high performance data processing processors like Digital Filter, Fast Fourier Transform, Discrete Cosine Transform, etc, and also be the key part of high performance data processing systems. The implementation is synthesizable Verilog code at the RTL level. It is suitable for real time video applications.

在MP3 解码电路中，模块IMDCT 由三个子模块组成：IDCT子模块、加窗函数子模块、输出数据的叠加子模块。N/2 点的输入Xk 经IDCT 变换得到N 点的输出xi 的公式如下：将输出根据不同的块类型(有四种块类型，分别为普通、开始、结束、短型)采用不同的窗函数加窗，得到一个36 个点的输出(对于块类型为短型的块，单个小块的输出是12 个点，每三个小块组合成一个36 个点的输出)。
