Bayesian Image Denoising with Multiple Noisy Images
Get PDFIn this paper, we propose a fast image denoising method based on discrete Markov random fields and the fast Fourier transform. The purpose of the image denoising is to infer the original noiseless image from a noise corrupted image. We consider the case where several noisy images are available for inferring the original image and the Bayesian approach is adopted to create the posterior probability distribution of the denoised image. In the proposed method, the estimation of the denoised image is achieved using belief propagation and an expectation-maximization algorithm. We numerically verified the performance of the proposed method using several standard images.journal articl

経験の語りと時間的経過から捉える英語学習動機の変容
Get PDFL2 learning motivation has received a lot of interest from language teachers and researchers in the field. It is unfortunate, however, that little attention has been paid to the dynamic fluctuation of language learning motivation. The aim of this study is to understand the fluctuation in the learning motivation of one Japanese learner of English through narratives of learning experiences. The data gathered through individual interviews was analyzed qualitatively by means of Personal Attitude Construct (PAC) Analysis and Trajectory Equifinality Approach (TEA). This study focused on the period of time when the learning motivation underwent a drastic change. The results of the study revealed the particular social factors that had an effect on the learner's motivation and demotivation with regards to English language learning. What is more, this study shows that the learner’s beliefs and values about the purpose of English learning were affected by various perspective changing encounters with both influential role models, and with other learners in the same environment that resulted in comparisons.journal articl
