This repository hosts a suite of tools and algorithms aimed at enhancing the resolution of images. We strive to provide clearer and more detailed visual data, which can significantly improve data analysis and research outcomes in various fields.
Deblurring by pixel reassignment (DPR) is to perform PSF sharpening similar to deconvolution but in a manner less prone to noise-induced artifacts and without the requirement of a full model for the PSF. The basic principle of DPR is to reassignment the intensity value of pixels post-image acquisition. The pixel reassignment step size is dependent on the local log-image gradient. DPR relies solely on pixel reassignment. As such, no negativities are possible in the final image reconstruction. Moreover, intensity levels are rigorously conserved, with no requirement for additional procedures to ensure local linearity.
