1. This paper mainly discusses the problem of differential model identification using real-time Recursive Orthogonal Transform (Householder Exchange) in 2D digital signal processing, and real-time recursive algorithm of two-dimensional differential model structure and parameter identification is derived. This algorithm is based on the discussion of two-dimensional IIR digital filter time-domain design. Computer simulation results show that this method not only has high precision, but also achieves the simultaneous identification of model order and parameters, and can be recursive in real time, greatly
