Give me your digits!: digit database

The mnist database

We used a database as a reference for comparing sample inputs. The database is a modified database from the National Institute of Standards and Technology (MNIST) database of handwritten digits. More specifically, we downloaded the database from http://yann.lecun.com/exdb/mnist/ and converted the database into Matlab format using code from http://www.cs.toronto.edu/~hinton/code/converter.m.

The format of the images in the MNIST database is a 20 by 20 grayscale image centered in a 28 by 28 box using its center of mass. The training set of the database is composed of ~60,000 (5,000 images/dig) images compiled from ~250 writers. The test database is disjoint form the training set and is composed of ~10,000 images (1,000 images/dig). This database was designed by computer scientists for the analyzing of classifiers (identification algorithm).
