通过极坐标变换获得中心投影曲线，从而利用中心投影进行图像分割。(Polar coordinates obtained by central projection curve to using a central projection for image segmentation.)

说明：  延迟对象的PID控制的方波响应。将滤波输出作为给定信号，可使方波响应和执行器的动作更加平稳，在工程上具有很大的意义。(PID Controler for Square Tracking with Filtered Signal)

communication system is expected to increase the service, the quality improvement and also the capacity, using spread spectrum communication system is one of the method to fulfill that demand. This quality and capacity factor will depend on the number of user. In order to see the performance of the Wiener Filter on the MC-CDMA system, simulation method is used by increasing the Direct Sequence Spread Spectrum CDMA signal, with digital modulation QPSK
