This article investigates the issues of improving the verification accuracy by improving the quality of digital signature images in offline signature verification systems. During the study, the impact of factors such as noise, low contrast, and image deformations in signature images on the verification process was analyzed. The quality of signature images was improved by using image preprocessing, filtering, binarization, and morphological processing algorithms. The effectiveness of median and Gaussian filters was evaluated based on the CEDAR Signature Dataset and BHSig260 databases. CNN and One-Class Support Vector Machine (OCSVM) algorithms were used at the verification stage.
