The MNIST database of Handwritten upper-case letters is a subset derived from NIST Special Database 19 Handprinted Forms and Characters Database, and developed at IDIAP. It comprises the image files of handwritten upper-case letters, which have been size-normalized and centered in a fixed-size image. Generally the image files were written in SVM-Torch format, it's convenient for the Torch users, it's also easy to transfer it into other format. There is software attached with INIST, which used to get visiable image files.
