Classic adaptive binarization methodologies threshold pixels intensity with re-spect to adjacent pixels exploiting integral images. In turn, integral imagesare generally computed optimally by using the summed-area-table algorithm(SAT). This document presents a new adaptive binarization technique basedon fuzzy integral images. Which, in turn, this technique is supported by anefficient design of a modified SAT for generalized Sugeno fuzzy integrals. Wedefine this methodology as FLAT (Fuzzy Local Adaptive Thresholding). Exper-imental results show that the proposed methodology produced a better imagequality thresholding than well-known global and local thresholding algorithms.We proposed new generalizations of different fuzzy integrals to improve existingresults and reaching an accuracy≈0.94 on a wide dataset. Moreover, due tohigh performances, these new generalized Sugeno fuzzy integrals created ad hocfor adaptive binarization, can be used as tools for grayscale processing and morecomplex real-time thresholding applications.
