If singular value curve is convex in the coordinates 'k' of maximum peak of curvature spectrum, then the number of effective singular values is k; if singular value curve is concave in the coordinates 'k', then the number of effective singular values is k-1, and this rule is tested by the signal processing examples.
如果奇异值曲线在曲率谱最大峰值的位置坐标k处是凸出的,则有效奇异值的个数为k;如果奇异值曲线在k处是凹进的,则有效奇异值的个数为k-1,通过信号处理实例证实了这种结论。
