A generalization of Otsu method for linear separation of two unbalanced classes in document image binarization [PDF]

open access: yesКомпьютерная оптика, 2021
The classical Otsu method is a common tool in document image binarization. Often, two classes, text and background, are imbalanced, which means that the assumption of the classical Otsu method is not met.

Parametric modeling of visual search efficiency in real scenes.

open access: yesPLoS ONE, 2015
How should the efficiency of searching for real objects in real scenes be measured? Traditionally, when searching for artificial targets, e.g., letters or rectangles, among distractors, efficiency is measured by a reaction time (RT) × Set Size function ...
