要求设计一个基于颜色直方图的图像检索系统。该系统能够实现对图像的检索功能，例如，在一万幅图像中搜索出与检索图像相似的图像，依相似程度的大小显示出来。最后用查全率和查准率对系统进行评估。(To design a color histogram based image retrieval system. The system can realize the image search function, for example, a square image search and retrieval of an image similar to the image size according to the degree of similarity is displayed. Finally, recall and precision to evaluate the system.)

最近用Mega128写了一个128点FFT程序，浮点运算，加汉宁窗。由于窗函数和旋转因子通过查表得到，所以速度还可以，程序中给的初值是通过高速AD采集的20KHz正弦信号。计算结果与Matlab的FFT函数得到的结果相同。 (Mega128 recently wrote a 128-point FFT procedures, floating-point operations, Hanning window. Since the window function and the twiddle factor look-up table has been adopted, so the speed can also be, the initial value to the process through high-speed AD collected 20KHz sinusoidal signal. The calculation results with the Matlab)
