查询词典 feature

The import picture feature is useful for displaying graphics from other applications in your drawing. For example, a cross-section drawing could be imported as a DXF file from AutoCAD for use as a background graphic while defining the problem domain. This feature can also be used to display things like photographs or a company logo on the drawing. Pictures are imported as an AutoCAD DXF file, a Windows bitmap file, an enhanced metafile, or a Windows metafile,.

重要的图片特征便于从图中其他应用中显示图形，例如，当定义模型要素时，一个网格部分可以输出为DXF文件便于AutoCAD作为图纸背景使用，这种特征也可被用来在图中显示比如图片或公司logo，图片可以被输出为：AutoCAD DXF、BMP、EMF、WMF等格式。

In the matching stage, the angle of feature vectors is used as the similarity measure in the high dimensional space directly. This similarity measure is invariant to the linear transformation of feature vectors. Compared with SIFT and normalized correlation, the proposed method needs no primary features such as edges, corners, gradient or shapes which are very unstable in low contrast and low NSR images.
