Abstract :
The authors summarize the application of several signal processing techniques. These include: (1) reconstructing the electrical potential on an active layer of cells from surface measurements using 2-D filtering; (2) identifying locations of still-active layers following myocardial infarction using a multiple-hypothesis generalized likelihood ratio test; and (3) estimating the location of a single still-active layer by maximum likelihood estimation, and determining the Cramer-Rao bound for the mean-square estimator error.<>
