can you count the letter m in:
this correspondence is concerned with the development of a recursive identification and estimation procedure for 2-d block kalman filtering. the recursive identification scheme can be used on-line to update the image model parameters at each iteration based upon the local statistics within a block of the observed noisy image. the covariance matrix of the driving noise can also be estimated at each iteration of this algorithm. a recursive procedure is given for computing the parameters of the higher order models. simulation results are also provided.
