Özet
We have investigated the stability problems observed in multichannel multidimensional linear predictive modeling of images. It is known that based on a positive definite autocorrelation matrix, singular values of the matrix H = delta(i+1)center dot Herm (delta(i+1)) must lie inside the unit circle for a stable solution, where delta(i+1) is the normalized partial correlation matrix and Herm denotes the Hermitian operator. We have developed a two-step stabilization method to obtain stabilized linear prediction coefficients for short term analysis windows formed digitized images. We have modified the multichannel Levinson recursion algorithm to include this stability procedure. We have tested our algorithm on numerous images commonly used in image coding and the results are very impressive.
