Here, we report a method for estimating the MTF\nfrom sample images. Test images were generated from a number of images,\nincluding those taken with an electron microscope and with an observation\nsatellite. These original images were convolved with point spread functions\n(PSFs) including those of circular apertures. The resultant test images were\nsubjected to a Fourier transformation. The logarithm of the squared norm of the\nFourier transform was plotted against the squared distance from the origin.\nLinear correlations were observed in the logarithmic plots, indicating that the\nPSF of the test images can be approximated with a Gaussian. The MTF was then\ncalculated from the Gaussian-approximated PSF. The obtained MTF closely\ncoincided with the MTF predicted from the original PSF. The MTF of an x-ray\nmicrotomographic section of a fly brain was also estimated with this method.\nThe obtained MTF showed good agreement with the MTF determined from an edge\nprofile of an aluminum test object. We suggest that this approach is an\nalternative way of estimating the MTF, independently of the image type.","url_abs":"http://arxiv.org/abs/1711.09776v1","url_pdf":"http://arxiv.org/pdf/1711.09776v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"method-for-estimating-modulation-transfer","repo_url":"https://github.com/mizutanilab/RecView","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
