ÒSENCORPÓ Recipe
1.Smooth Pb = P1b
2.Element-wise cube of  P1b  = P2b
3.Normalized matrix product of P2b with itself = P3b
4.Use element-wise square of P3b to compute K.
HereÕs a recipe for how their adaptive scheme works.
True covariance shown if top right (temporal separation, two peaks)

1)Spatially smooth
2) cube
3) Matrix product
