TIS, the Thoracic Identification System
TIS is a thoracic signal biometric identification program written in matlab. The software was orignally written for the Intelligence Community under an IC Fellowship grant (2011 - 2013) at Clarkson University. The program works on ECG and carotid pulse signals. The software computes feature sets following the algorithms in Chen, et.al [1] and classifies the testing feature sets against the training feature sets using either a probabilistic classfier or the support vector machine provided by LIBSVM [2].
