Nonparametric mine line detection using spatial analysis
A mine line detection method to identify mine-like contacts (MLCs) that fit into mine line patterns dictated by standard mine laying protocol. In general, MLCs define a minefield where the minefield has both mines and false alarms. The method classifies every MLC into one of three classes: fixed—a mine line pattern with fixed mine spacing; random—a mine line pattern with random mine spacing; or false alarm—the MLC does not fit into a mine line pattern and is not considered a mine. The method requires no knowledge of either the sensor probability of detection (Pd) or probability of false alarm (Pfa); nonetheless, it significantly improves both. A nonparametric anomaly detector identifies regions with unusually high MLC density for more detailed analysis. Suspected regions are analyzed for unusually regular patterns of MLCs. Probabilities that the observed target densities and target patterns could occur by chance are estimated. |

Unnatural prosody detection in speech synthesis
Described is a technology by which synthesized speech generated from text is evaluated against a prosody model (trained offline) to determine whether the speech will sound unnatural. If so, the speech is regenerated with modified data. The evaluation and regeneration may be iterative until deemed natural sounding. For example, text is built into a lattice that is then (e.g., Viterbi) searched to find a best path. The sections (e.g., units) of data on the path are evaluated via a prosody model. If the evaluation deems a section to correspond to unnatural prosody, that section is replaced, e.g., by modifying/pruning the lattice and re-performing the search. Replacement may be iterative until all sections pass the evaluation. Unnatural prosody detection may be biased such that during evaluation, unnatural prosody is falsely detected at a higher rate relative to a rate at which unnatural prosody is missed. |

Finite dataset interpolation method
The invention provides a fast method for a high-quality interpolation of a finite multidimensional dataset. It has particular application in digital image processing, including, but not limited to, processing of both still images and real-time image/data processing. The method uses discrete cosine and sine transforms of appropriate types to covert, in blocks of desired size, the initial dataset to the frequency domain. Proposed interpolators calculate a chain of inverse transforms of non-square sizes that perform the interpolation. The larger transform is broken into smaller transforms of non-square size using a recursive size reduction process of FFT-type, and the smaller transforms are calculated directly exploiting the symmetry properties of smaller interpolator functions involved. An output dataset is then assembled using the calculated transforms. The method avoids computationally costly process of inflating the coefficient space by padding zeros exploited for DCT-based interpolations previously. |
