gpdsHMM

A Hidden Markov Model (HMM) Toolbox within the Matlab environment is available. In this toolbox, the conventional techniques for the continuous and discrete HMM are developed for the training as well as for the test phases. The ability to make different groups of components for the vector pattern is provided. Multi-labeling techniques for the discrete HMM is also provided. The toolbox includes procedures suitable for the classical applications based on the HMM, as pattern recognition, speech recognition and DNA sequence analysis.

 

This toolbox is distributed as binary (dll files) and source code format. For a wide promotion, we ask the users to make a reference to the paper:

gpdsHAND

GPDS150hand database

 

Our database consists of 10 different acquisitions of 150 people by a desk scanner. The 1500 images have been taken from the users’ right hand. The user in our system can place the hand palm freely over the scanning surface; we do not use pegs, templates or any other annoying method for the users to capture their hands.

 

The signatures are in "jpg" format, 256 gray levels and 120 dpi of resolution. The files of the hands are named xxx\manoxxx_yy.jpg where xxx is the number of the signer and yy its repetition.

gpdsSIGNATURE

GPDS300signature database

 

Off line signature database. It contains data from 300 individuals: 24 genuine signatures for each individual, plus 30 forgeries of his/her signature. The 24 genuine specimens of each signer were collected in a single day writing sessions. The forgeries were produced from the static image of the genuine signature. Each forger was allowed to practice the signature for as long as s/he wishes. Each forger imitated 3 signatures of 5 signers in a single day writing session. The genuine signatures shown to each forger are chosen randomly from the 24 genuine ones. Therefore for each genuine signature there are 30 skilled forgeries made by 10 forgers from 10 different genuine specimens.

 

The signatures are in "bmp" format, in black and white and 300 dpi. The files of the genuine signatures are named xxx\c-xxx-yy.bmp and the files of the forgeries are named xxx\cf-xxx-yy.bmp where xxx is the number of the signer and yy its repetition.
