由于噪声点(灰度与周围点相差很大的点)对边沿检测有一定的影响，所以效果更好的边沿检测器是高斯拉普拉斯(LOG)算子。它把我们在第3章中介绍的高斯平滑滤波器和拉普拉斯锐化滤波器结合了起来，先平滑掉噪声，再进行边沿检测，所以效果会更好。
As the noise points (points, a big difference with the surrounding gray points) on the edge detection to a certain extent, the effects are therefore a better edge detector is the Laplace Gaussian (LOG) operator. It is our described in Chapter 3 of the Gaussian smoothing filter and Laplacian sharpening filter combines first smooth out the noise, and then to edge detection, it would be more effective.

做DSP最应该懂得157个问题（回答） 四.5V/3.3V如何混接？ TI DSP的发展同集成电路的发展一样，新的DSP都是3.3V的，但目前还有许多外围电路是5V的，因此在DSP系统中，经常有5V和3.3V的DSP混接问题。在这些系统中，应注意： 1)DSP输出给5V的电路（如D/A），无需加任何缓冲电路，可以直接连接。 2)DSP输入5V的信号（如A/D），由于输入信号的电压>4V，超过了DSP的电源电压，DSP的外部信号没有保护电路，需要加缓冲，如74LVC245等，将5V信号变换成3.3V的信号。 3)仿真器的JTAG口的信号也必须为3.3V，否则有可能损坏DSP。 五.为什么要片内RAM大的DSP效率高？ (2008-07-18, WORD, 25KB, 下载36次)

自动控制理论是人类在了解自然和改造自然的过程中逐渐形成的一门学科。简单反馈控制的最早应用，可以追溯到古代亚历山大时期的克泰希比斯水钟，它就是利用反馈原理来调节流量的。19世纪中叶，J.C.麦克斯威尔对具有调速器的蒸汽机（这也利用了反馈原理来调速）系统进行了稳定性的研究。20世纪20年代，布莱克、奈奎斯特和波德在贝尔实验室的一系列研究工作奠定了经典自动控制（反馈）的理论基础------
