Overview on Super Resolution Image Reconstruction

Super-resolution image reconstruction technique produces a high-resolution image from several low-resolution images,can also eliminate additive noise and the distinction which has been come from limited detector of size and optical components.Therefore,it has been a lot topic in the field of image processing.Introduces the basic principle of super-resolution reconstruction technique,and classifies the classical method based on single frame and multi frame,the frequency domain and airspace.Systematically summarizes the advantages and disadvantages of various methods and provide theoretical basis for the super-resolution reconstruction technique of further research,and puts forward the research direction of super-resolution reconstruction technique.
