Abstract
A new noncausal model which can be implemented recursively is peoposed in this paper to overcome the disadvantage of being unable to be implemented recursively. The corresponding estimation algorithm is also suggested and is an asymptotic method. Many experimental results confirmed the validity of our model. It can replace the common noncausal model to do image feature extraction
