Get reduce the size of an original sound file between half to three quarters of the initial size. The FLAC format is often used to sell music online, and as an alternative to MP3 to share when you want to reduce the file size would have

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.)

Koch曲线是通过图形迭代的方式产生的，其迭代规则是：对一条线段，首先将它分成三等份，然后将中间的一份替换成以此为底边的等边三角形的另外两条边。无限次迭代下去，最终形成的曲线就是Koch曲线。(Koch curve is generated by way of graphical iteration, and its iteration rule is: for a segment, it is divided into three equal parts first, and then replace the middle of a bottom side of this equilateral triangle to the other two edges. Infinite iterations continue, the final form of the curve is the Koch curve.)
