BCSD: Bank Checks Segmentation Database

December 16, 2020

This dataset consists of 158 images of bank checks labeled with segmentation masks for handwritten signatures on the checks.

Contents

Images of bank checks were obtained from different sources (as listed below), and resized such that the longer side of each image is 2240px with a resolution of 300px/in. All images were also converted to JPEG format. Segmentation masks for the signatures on these checks were manually created, and the dataset was divided into 129 training images (82%) and 29 test images (18%).

Most of the checks have one signature each, but there are a few with more than one signature per image. The 29 images in the test set were all taken from Google Image Search. These images were lower quality than the images in the test set, and were scaled up when resizing in the preprocessing step. Therefore, the test set is inherently more difficult to segment than the training set.

Purpose

It was created to train a network for signature extraction from bank checks.
