用模最大值法提取小波脊，该例中又两条小波脊，所以是多脊提取。同时又施加惩罚函数，控制lamda的值，可以得到较为平滑的小波脊。( using maximum modulus extract wavelet ridge, the case has two wavelet ridge, it is a multi-ridge extraction. At the same time to impose the penalty function to control the value of lamda,the extracted ridge can be relatively smooth .)
