Abstract

The present disclosure provides an image repairing method, device, electronic device and storage medium. The image repairing model is trained by constructing a sample image data set consisting of a scanning tunneling microscope differential conductance map, a scanning tunneling microscope topography map and texture image data; Configure a defect mask and the corresponding mask spectrum for the image to be repaired to indicate dense and discrete defect location areas; input the image spectrum and mask spectrum of the area image corresponding to the defect location area into the trained frequency domain convolution network to obtain the preliminary repaired image corresponding to the area image; input the preliminary repaired image to the trained detail repair network to obtain the detail repaired image corresponding to the area image; replace the image of the defect location area in the image to be repaired with the detail repaired image, A repaired scanning tunneling microscope image was obtained. For scanning tunneling microscope images with high density texture details and periodicity, dense and discrete defects can have a better repair effect.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image restoration method, apparatus, electronic device and storage medium. Background technique [0002] As an imaging tool with atomic-level high resolution, Scanning Tunneling Microscope (STM) has been widely used in many fields, including energy, optoelectronics, electronics, and quantum information. Through quantitative topography or differential conductance scanning of the surface, the acquisition, analysis and evaluation of characteristic information such as material microstructure and local electronic state can be achieved. The tunneling current detected by STM is generally in the order of nanoamps (nA), so the requirements for the environment are also very strict, and slight vibration and electromagnetic interference will have a great impact on the scanned image. On the other hand, there are also some natural intrinsic defects on the surface of ...
