| Abstract: | A top to bottom method of feature extraction base on knowledge is presented. By the analysis of target infrared features, first the three dimension gray plane image is projected into two two dimension images, then the edge, angle and area features can be extracted respectively? These features are syncretized to obtain the plane's features. The conclusion expresses that the complexity of feature extraction system is simplified obviously and the circuit is easy to implementation? |
