sg 滤波器： Savitsky Golay filter

库

github 上面可用的库有两个：

• savitzky-golay-filter: https://github.com/ruozhuochen/savitzky-golay-filter https://github.com/raghupati1996/Android-App-Accelerometer-using-Savitzky-Golay-filter-
• jDSP: https://github.com/psambit9791/jDSP

资料

• savitzky-golay-filter 这个暂时没找到资料
• jDSP https://github.com/psambit9791/jDSP/wiki/Savitzky-Golay-Filter

使用问题

• savitzky-golay-filter 这个需要配套的是 math v2.2
• jDSP 需要需改 gradle 文件，否则会报错。
