Online handwritten Uighur word tilt correction method

The invention discloses an online handwritten Uighur word tilt correction method, which adopts some basic preprocessing operations on Uyghur online handwritten word samples, including point insertion,multi-layer smoothing and point distance sampling. The method performs preprocessing in units of strokes in view of the fact that the basic pre-processing operation directly on the overall handwritten word track will generate additional noise or loses key information points. In order to solve the common tilt correction problem of handwritten words, the present invention proposes a tilt correctionalgorithm based on a block center. The algorithm is simple to implement, is fast in speed, and has a good tilt correction effect. The algorithm can be directly extended to handwritten words of otherpinyin texts and text line tilt correction. 本发明公开了种联机手写维吾尔文单词倾斜矫正方法，该方法在维吾尔文联机手写单词样本上采用了些基本的预处理操作，包括点插入，多层平滑和点距离抽样等。考虑到在整体手写单词轨迹上直接采用基本预处理操作会产生额外噪声或失去关键信息点，本发明以笔画为单位进行预处理。为解决手写单词常见的倾斜矫正问题，本发明提出种基于区块中心的倾斜矫正算法。此算法实现简便，速度快，倾斜矫正效果好
