feature extractor meaning in English

特征抽取程序

In feature extractor , the paper combines centriod of the moving objects to tracking window to distinguish pedestrian and moving vehicle . similar functions are applied for matching feature
在特征提取方面，采用了质心和窗口相结合的方法，兼顾了目标的位置和形状；而且还初步的去除了行人对运动目标跟踪的干扰。
The multiscale mixed distribution models ( mmdm ) and the multiscale autoregressive ( mar ) models are investigated in this thesis , and they are applied to the unsupervised segmentation of the synthetic aperture radar ( sar ) image by joining them together - the multiscale mixed distribution models as the feature extractor and the multiscale autoregressive models as the classifier
本文对多尺度混合分布模型( multiscalemixturedistributionmodels简记mmdm ) ，其中主要是对多尺度混合gauss分布模型( multiscalemixturegaussianmodels简记mmgm )和多尺度混合rayleigh分布模型( multiscalemixturerayleighmodels简记mmrm )进行了研究，及对多尺度自回归( multiscaleautoregressive简记mar )模型进行了研究，并将mmdm作为图像分割的分类器， mar模型作为图像分割的特征提取器对合成孔径雷达( syntheticapertureradar简记sar )图像无监督分割进行了研究。
