Description
Summary:Interpolation methods face the issue of the specific content of the images. This paper is devoted to a comparison of interpolation methods suitable for small image content and its influence on improvement in the PSF estimation. The issue is that when the PSF is represented by only several pixels, the model of the system is not correctly optimized. Selection of the suitable interpolation method represents the main aim with consequences to the PSF model estimation.
