针对超低剂量成像中机器学习去噪产生伪影的问题,本文提出将时间序列图像分解为空间二维图像与时间轴再进行去噪的方法,实现低剂量条件下连续高分辨率图像的准确稳定重建。

摘要:

数字图像设备已广泛应用于科学成像、个体识别和遥感等多个领域。随着这些成像技术在自动驾驶和测量中的应用,在无法以足够剂量进行观测时产生的图像噪声已成为一个主要问题。机器学习去噪技术有望成为该问题的解决方案,但存在以下问题。本文以电子显微镜的原位观测视频为例,报告了在超低剂量观测中由机器学习去噪产生的伪影。作为解决该问题的方法,我们提出了一种将时间序列图像分解为空间轴二维图像和时间轴并进行机器学习去噪的方法。我们的方法为科学、工业和生活中从低剂量成像中准确稳定地重建连续高分辨率图像开辟了新途径。

英文摘要:

Digital image devices have been widely applied in many fields, including scientific imaging, recognition of individuals, and remote sensing. As the application of these imaging technologies to autonomous driving and measurement, image noise generated when observation cannot be performed with a sufficient dose has become a major problem. Machine learning denoise technology is expected to be the solver of this problem, but there are the following problems. Here we report, artifacts generated by machine learning denoise in ultra-low dose observation using an in-situ observation video of an electron microscope as an example. And as a method to solve this problem, we propose a method to decompose a time series image into a 2D image of the spatial axis and time to perform machine learning denoise. Our method opens new avenues accurate and stable reconstruction of continuous high-resolution images from low-dose imaging in science, industry, and life.
