查询词典 sample method

This method uses K-L transform to produce matrix of sample aggregate, get a low dimension sub space to describe the wrist bone's radiographs. Each image makes projection, and obtains one group of coordinate coefficients. The coefficients indicating the position of this image in sub space can be discerned the image feature.

该方法通过对由中指骨组成的训练样本集的产生矩阵做K-L变换，用一个低维子空间来描述中指骨X光图像，每幅图像向其作投影，并获得一组坐标系数，这组系数表明了该图像在降维子空间中的位置，能较好地表征该幅图像的特征信息。
