description: The given work is devoted to research on the application of interpolation in image processing. Image interpolation is one of the most basic image processing techniques that has been widely studied and applied. Based on this technology, image processing techniques can be improved in software to obtain higher image quality. In this section, I first introduced four working principles of nearest neighbor interpolation, bilinear interpolation, bicubic interpolation, and cubic B-spline interpolation. Then use Matlab to program these four interpolation methods accordingly to enlarge the image. Finally, subjectively and objectively compare the results of the magnified and processed images using these four interpolation algorithms, and compare the sharpness of the processed images subjectively with the naked eye, and again use Matlab to write a program to calculate the image sharpness before and after processing, and the processor efficiency for four algorithms.
