Abstract:
A process for determining the overall false alarm probability when using histogram matching comprising the process actions of:generating a prototype histogram from a model of an item being sought in an environment; determining the set of all possible test histograms that can be formed from the environment given a prescribed number of bins and a maximum count for the bins; determining the subset of test histograms from said set of all possible test histograms, which will cause a false alarm, said false alarm occurring when a histogram formed from the environment matches the prototype histogram when that histogram does not actually represent the model of the item being sought; determining the probability of occurrence of each individual test histogram that will cause a false alarm in said subset; and summing the individual false alarm probabilities of occurrence of all histograms in said subset of test histograms which will cause a false alarm to establish the overall false alarm probability.
