你说呢...

物体识别算法中haar特征haar怎么读呀

3，什么是haar特征

这里有详细的说明：http://blog.csdn.net/cy513/archive/2009/06/20/4285579.aspx

什么是haar特征

4，什么是HAAR小波

Haar基本小波函数定义在区间 [0，1]上，如图所示：该基本小波定义的小波变换称为Haar小波变换，是常用的小波变换中最简单的一种。

5，如何画出haar和db小波基函数

你看的是小波变换和motion信号处理（二），如果你看了（一）就知道咋算了。按它的算法，内积是两个数组对应位置元素相乘再求和。psi（2n）的式子只看不是0的元素（因为0的乘积与求和还是0对最终内积的计算没有影响），值为1/2根号2的2个（n为1、2时，这里为了方便讲解n一般可以认为取整数，实际上是为了离散化取的个数），值为－1/2根号2的2个（n为3、4时），它自己的内积为1/2根号2×1/2根号2＋1/2根号2×1/2根号2＋（－1/2根号2×－1/2根号2）＋（－1/2根号2×－1/2根号2）＝1/8＋1/8＋1/8＋1/8＝1/2，不等于1，按它的解释就不归一化正交了。而乘上根号2，根号2×psi（2n）这个新函数的内积按照上面的计算是1/4＋1/4＋1/4＋1/4＝1，应该就归一化正交了。原始haar的数学定义值是1、－1和0，主要是定义域为[0,1/2)和[1/2,1)，不仅正交还归一化了。对于内积的计算如果是离散的向量，就用如上面的计算方式，如果是数学上的无限函数的连续值，就要计算积分了，haar很简单，按照积分的意义就是曲线与X轴围城的面积，从haar的图形面积就是1。不过其它正交小波函数可不一定为1，也就是不一定都归一化。上面的例子也是为了方便说明而已，其设定和理解还有些方面需要讨论，凑活意会吧！水平有限，仅供参考。

6，求哈尔的正确英文翻译

Howl

an eighteen years old girl soffe managed a hat store that passed down from his father. one day,a boy with beautiful yellow hair helped soffe when she got into a trouble. unexpectedly, the boy was said to be hall ,who was a bad boy and was good at stealing girls hearts. a switch who wanted to get halls heart swore at soffe to make her become a very ugly aged woman.soffe set up in halls castle since then. and they made an agreement to help each other to get away from the swear.halls teacher forced hall to make a fight between the two, but he refused. at the same time he also pulled himself into a dangerous situation. they got into a panic and felt uncomfortable.at the end, soffy managed to make them escape from hardship, and tried her best to help hall return to his life. and finally she came back to the time when hall met kasifa when he was young. she also got the heart back from the switch who lost her consciousness at the nick of the time. their love for each other moved halls teacher. what was more; they broke the switch from the switch and returned back to normal.at the last of the movie, sofie and hall stood at the mystery castle, receiving best wishes from the people. behind them was grassland blew by slight wind. all thing was prefect. 主人公的名字不知道对不对~嘿嘿~
