Kami mencadangkan model medan rawak Markov yang boleh diselesaikan baharu untuk pemprosesan imej Bayesian dan memberikan ungkapan tepat kebarangkalian marginal dan imej yang dipulihkan dengan menggunakan formula Gaussian berbilang dimensi dan transformasi Fourier diskret. Model medan rawak Markov yang dicadangkan termasuk model autoregresif bersyarat dan model autoregresif serentak sebagai kes khas. Anggaran hiperparameter diperoleh dengan memaksimumkan kemungkinan marginal. Kami mengkaji beberapa sifat statistik bagi model medan rawak Markov yang boleh diselesaikan. Dalam beberapa eksperimen berangka untuk imej standard, kami menunjukkan bahawa model medan rawak Markov yang dicadangkan berguna untuk aplikasi praktikal dalam pemulihan imej. Penyiasatan pemprosesan maklumat kebarangkalian melalui model kebarangkalian boleh diselesaikan baru-baru ini sedang dijalankan bukan sahaja untuk pemprosesan imej tetapi juga untuk kod pembetulan ralat dan sebagainya. Model kebarangkalian boleh diselesaikan memberi kita beberapa aspek penting untuk ketersediaan sistem pengiraan kebarangkalian.

Abstract: We propose a new solvable Markov random field model for Bayesian image processing and give the exact expressions of the marginal likelihood and the restored image by using the multi-dimensional Gaussian formula and the discrete Fourier transform. The proposed Markov random field model includes the conditional autoregressive model and the simultaneous autoregressive model as a special case. The estimates of hyperparameters are obtained by maximizing the marginal likelihood. We study some statistical properties of the solvable Markov random field model. In some numerical experiments for standard images, we show that the proposed Markov random field model is useful for practical applications in image restorations. The investigation of probabilistic information processing by means of a solvable probabilistic model is recently in progress not only for image processing but also for error correcting codes and so on. The solvable probabilistic model gives us some important aspects for the availability of probabilistic computational systems.
