*(CLOSED SOURCE: Pl. do not mail with requests for code). This tool provides a graphical user interface for fingerprint recognition. The tool enables visualization of matched minutiae. It also allows the user to identify new matched pairs or remove false correspondences. The windows setup program and sample data can be downloaded from here. The feature extraction code was contributed by Chaohang Wu (formerly at UB)  980k v. 1 Jan 21, 2009 4:00 PM Sharat Chikkerur

*CLOSED SOURCE (Pl. do not mail with request for code)* This tool provides a graphical user interface for minutiae feature extraction and visualization. It also allows the user to manually identify new minutiae or remove spurious ones. This tools was used by us to evaluate the efficiency of different feature extractors.The windows setup program and sample data can be downloaded from  983k v. 1 Jan 21, 2009 3:58 PM Sharat Chikkerur

Speaker ID using MFCC features : This is the source code and report for my machine learning class project at MIT. The source code implements MFCC and VQ/GMM based speaker identification system. Also provides an option to learn optimal number of cluster centers based on Bayesian Information Criterion. The matlab source code can be downloaded from here. The zip file also contains the project report that you may find helpful  143k v. 1 Jan 21, 2009 3:54 PM Sharat Chikkerur
