Paper Abstract

This article describes an approach to quantify the quality of thresholding-based segmentation on Brazilian bankchecks. The checks are previously acquired by scanner and soon after, their colored patterns are decomposed according to the HSI model. Several thresholding algorithms are then applied and an automatic evaluation of the results is carried out. The evaluation methodology is based on `performance assessment' of the character recognition rate from an optical character recognition.
