余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

、改写例程，编制用Fisher线性判别方法对三维数据求最优方向W的通用函数。
2、对下面表3-1样本数据中的类别ω1和ω2计算最优方向W。
3、画出最优方向W的直线，并标记出投影后的点在直线上的位置(Rewriting routine, the preparation of Fisher linear discriminant method using three-dimensional data on the direction of seeking the best general-purpose function of W. 2, for the following sample data in Table 3-1 in the categories of ω1 and ω2 to compute the optimal direction of W. 3, draw the best straight line the direction of W, and mark out the projection of the points in a straight line after the location of)

对于指纹图像,无论在频域或是在空域处理时,都要用到指纹的方向性信息,所以求取指纹方向图就显得格外重
要。求取指纹图像方向图的方法有很多种,文中列出了其中几种易于实现的算法。目的在于比较几种求取方向图的算法,
得到这几种方法的性能,以利于不同场合的要求。(good
