Abstract

This paper presents a new algorithm for filtering images of Brazilian bank checks. These images were generated by ATM machines and they present several kind of noise imposed by the digitization process. A new wavelet-based filtering algorithm is proposed for these images allowing a more efficient binarization process using percentage of black thresholding method.
