Abstract: A method and apparatus for automatically decomposing an audio object into a relational structure develops a hierarchically arranged folder. A user defines a characteristic of interest and the system locates each occurrence of the characteristic within the object. Each occurrence of the specified characteristic is separated from an adjacent occurrence by a segment of the object, thereby defining a segment length. A set of user defined isochronous transposition rules then arranges the segment lengths as a hierarchical folder structure.

Abstract: Method of, and apparatus for, optical character recognition of predominate and non-predominate color coded characters based on hypothesis testing utilizing both geometric optical character recognition and color coded optical character recognition techniques. In this hypothesis testing technique, geometric OCR is used to generate a null hypothesis that a target character has been recognized, and an alternative hypothesis that the target character has not been recognized. Color coded OCR is used to select either the null hypothesis or the alternative hypothesis. Alternatively, the roles of geometric OCR and color coded OCR may be reversed such that color coded OCR is used for hypothesis generation, and geometric OCR is used for hypothesis selection.

Abstract: Color coding of characters both for optical character recognition by a machine and for viewing by a human is provided by coloring a character with a predominate color distinguishable by humans and a non-predominate color non-distracting to humans, but distinguishable by a color scanner. The advantage of the present invention is higher optical character recognition accuracy rates without the severe visual distraction to human readers of prior art color coded characters. A further technical advantage is that the invention can be practiced with conventional color printers and color scanners instead of the specialized apparatus of prior art color coded characters.

Abstract: Method of, and apparatus for, processing a color coded character to recognize the character being examined by an OCR device. Said color coded character comprises a predominate color associated with said character distinguishable by humans, and a non-predominate color associated with said character and non-distracting to humans, but distinguishable by a color scanner. The present invention allows the non-predominate color of a character to be used as the sole criteria for recognizing the character.
