Abstract

The invention provides an image reconstruction method and apparatus, and a computer readable storage medium. The method comprises the steps of obtaining a Fourier spectrum of an imaged object; and performing phase recovery on the Fourier spectrum by adopting an image reconstruction method fused with cuckoo search optimization to obtain recovered phase information, and outputting a final reconstructed image. According to the method, the device and the computer readable storage medium, the problems that an existing HIO-based image reconstruction method is sensitive to an initial value, the robustness of multiple reconstructions is poor, and the iteration process is prone to falling into local optimum can be solved.

Description

technical field [0001] The present invention relates to the field of image reconstruction, in particular to an image reconstruction method, device and computer-readable storage medium. Background technique [0002] At present, in order to restore the phase information of the Fourier spectrum in the light intensity interference imaging technology, the phase information of the Fourier spectrum is calculated based on iterative projection. This approach has achieved certain results, the most famous of which is the HIO (Hybrid Input-Output, mixed input and output) method. However, the HIO phase recovery method is sensitive to the initial value, the robustness of multiple reconstructions is poor, and the iterative process is easy to fall into local optimum, resulting in poor image reconstruction effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an image reconstruction method, device and computer-readable storage...
