ABSTRACT:
A multi-dimensional assemblage of time/velocity functions are sampled for velocity as a function of incremental time. The samples are stored in a matrix arranged in columns along the time axis and rows across the velocity axis. The count of the number of samples resident in the respective cells of each row is indexed. A desired statistical operator is applied to the count indices in the rows to provide a family of filtered histograms in time-sequential order. The filtered histograms may be edited by delimiting acceptable velocities to lie between preselected percentiles.
