A schematic overview of the proposed algorithm. (a) A raw image stack of typical XANES imaging data with significant image jittering and deformation. (b) The deep-learning-based image alignment method, including the forward generator of Cycle-GAN and optimized U-net. (c) A schematic illustration of the alignment XANES image stack. (d)–(g) A comparison of the stacked image and enlarged regions of interest before [panels (d) and (f)] and after [panels (e) and (g)] applying our registration method. |
