医学图像分辨率增强的目标是将低分辨率图像重建为高分辨率图像。本文提出了一种小波域的贝叶斯方法,利用贝叶斯推理框架对图像插值问题进行数学表述。此外,该方法对高分辨率图像的未知小波系数和小波系数统计模型的未知参数进行了联合估计。实验证明了该方法的优越性能。
The goal of medical image resolution enhancement is to reconstruct a higher-resolution image from its lower-resolution counterpart. This paper proposes a Bayesian approach in the wavelet domain by exploiting a Bayesian inference framework to mathematically formulate the image interpolation problem. Furthermore, the proposed approach jointly estimates both the unknown wavelet coefficients of the high-resolution image and the unknown parameters of the statistical model for wavelet coefficients. Experiments are conducted to demonstrate the superior performance of the proposed approach.
