摘　　要：自适应滤波器是一个空间域的数字滤波器。它对不应作滤波处理的点不作滤波 ,使滤波过程对区域成分的畸变降到最小。它采用一元三点内插法作插值 ,使滤波公式简单 ,计算速度快而又能保证精度。判别局部成分的标志及滤波计算都只用到局部成分前二个点及后二个点 。The selt adapting filter is a filter in the space domain and can be used to separate the local and regional components in the data. The filter only works in the area where exists a local component. Thus it makes the distortion of the regional component to a minimum. It employs a short operator to complete the filtering precedure and to decrease the edge lost. The filter can be used to filter out given width local component or components less than a given value.
