As feature extraction acts an important role in pattern recognition system, we propose three novel feature extraction methods for HCCR: a、Two structural feature extraction methods, Stroke Cross Counting Features and Peripheral Features are studied. According to the characteristics of Chinese handwriting samples, we extend the SCCF and PF respectively to weighted elastic SCCF and weighted elastic PF. Experiments show that the modified feature extraction approaches are better than original approaches. b、A new statistical feature extraction method——Elastic Meshing Directional Decomposition Feature extraction is proposed. According to the stroke statistical properties of Chinese character, we first decompose a handwritten character pattern into four directional subpatterns. Then a set of elastic meshes are applied to each of the four subpatterns respectively to extract the pixel distribution features.

统计识别方法：利用统计模式识别的经典方法——Bayes分类方法来进行汉字识别的研究，特征提取是统计模式识别的关键，本文着重围绕手写体汉字的特征分析和提取方法进行了研究，提出了三种特征提取的新方法： a、两种改进的结构特征提取方法：在笔划密度特征和外围特征的基础上，结合手写体汉字的特点，提出了加权非均匀笔划密度特征、加权非均匀外围特征的特征提取新方案； b、一种新的统计特征提取方法——弹性网格方向分解特征，根据汉字方块字的特点及笔划分布的统计特征，对手写体汉字进行横竖撇捺四方向的分解，并利用一系列的弹性网格对汉字分解后各分量的象素进行统计而提取特征，实验证明该特征提取方法用来进行手写体汉字识别是十分可行和有效的。

When I was in the Just Jack hiphop label affixed, I also find themselves made a mistake, but I do not know how to correct such a mistake, started from the DJ Just Jack concerts give you a rap music Feeling, but also the United Kingdom than The Streets, Just Jack is right or more like a singing, and Just Jack has an indie folk singing voice, I would hope that he can really sing some of the flavor of a melody Works, but do not misunderstand me, it was precisely because in a beautiful album to add a lot of the rap part, seemed offensive, in the main song Starz In Their Eyes in, breakdance style of the song to song sounds More like a European dance music, the same Styles also reflected in another one song I Talk Too Much above, hiphop album of songs is another theme, the album from the start of the Glory Days, and then to Disco Friends and Lost Full of British-style hiphop, in more than half of the album, the album's tone and transferred to another like some indie, some folk feel, but also from time to time with some electronic elements, like this you have to listen to the music Hold On, that is, to the later, the album only gradually become the acoustic, into a sentimental, has become another Just Jack, Mourning Morning: Some of the flavor of the atmosphere, in particular, his included with the accompaniment of a string , The guitar more to increase the effectiveness of the appeal of the song, the album is the most outstanding works of the gas, and the last one of the songs have a similar Spectacular Failures of the same style, hidden track, and The Offspring of some punk rap categories have similar accidents .

当我在把 Just Jack 贴上hiphop标签之后，我发觉自己又犯了一个错误，但是我却不知道该如何去改正这样一个错误，从DJ起家的 Just Jack 的音乐会给你一种说唱音乐的感觉，但是比起同样是英国的The Streets， Just Jack 说得还是更像是唱，加上 Just Jack 有着一副唱indie民谣的嗓音，我倒希望他能够真正唱出一些有味道的有旋律的作品，但是也别误解我的话，正是因为在本来一张优美的专辑中加入了许多说唱的部分，所以显得有些唐突，在主打歌曲 Starz In Their Eyes 中，breakdance风格的曲子让歌曲听起来更像是一首欧洲舞曲，同样的曲风还体现在另外一首歌曲I Talk Too Much上面，hiphop的歌曲是专辑的另外一个主题，从专辑一开始的Glory Days，再到Disco Friends和Lost充满着英国式的hiphop，就在专辑过半的时候，专辑的基调又转到了另外一个样子，有些indie，有些民谣的感觉，还时不时加上一些电子的元素，喜欢这样的音乐你要听听Hold On，也就是到了后来，专辑才渐渐变成的acoustic，变成了sentimental，变成了另外一个 Just Jack ，Mourning Morning颇有些大气的味道，特别是他的配器加上了弦乐的伴奏，吉他的效果更加增加了歌曲的感召力，是专辑中最出色的作品之气，最后一首歌曲的Spectacular Failures同样有着类似的风格，hidden track和The Offspring的有些说唱类punk有着意外地相似。
