摘要
使用曲线拟合的方法对手写数据进行压缩,达到压缩目的。其步骤是:将坐标、压力等多个通道输入的手写数据与时间组合成二维数组,对数组数据进行曲线拟合,得到压缩结果。相对于将手写输入转换成图像的压缩方法,该方法有效地压缩记录手写输入的动作,可以还原出手写轨迹、速度等信息,能保持较高的压缩率。
Uses curve fitting method compress handwritten data to achieve compression purposes.The steps are：combines the coordinate,pressure and other handwritten input data with time to form twodimensional array,makes curve fitting of the array data to achieve compression results.Compares to the handwritten input into the image compression method,this method effectively compress the handwriting action,it can restore the hand trajectory,velocity and other information,and maintains a high compression ratio.
