These so-called consistent TFRs are developed by requiring the desired representation to be consistent with a set of spectrogram-based energy measurements. The desired representation is obtained as the solution to a constrained-optimization problem. The optimization problem can be solved using a gradient-projection technique. The consistent TFR demonstrates superior performance compared to existing techniques on a variety of test signals as well as on actual biological data. The result is a high-resolution, nonnegative, intuitively satisfying TFR that should prove to be an excellent tool for exploratory analysis. Made available in DSpace on 2015-09-25T20:08:14Z (GMT).
