Title: Innovations of Patrick C Leung
Introduction
Patrick C Leung is a notable inventor based in Waterloo, Canada. He has made significant contributions to the field of character recognition technology. With a total of 3 patents to his name, Leung's work has advanced the capabilities of systems that interpret and process written characters.
Latest Patents
One of his latest patents is for a system of matrix character recognition. This innovative character recognition system compares rows of binary signals representing an unknown character to a set of templates for known characters. The system performs sequential comparisons, shifting the rows of signals to detect characters that may be printed off-center. This method enhances the accuracy of identifying unknown characters by focusing on essential feature characteristics.
Another significant patent by Leung is the matrix character reading system. This invention involves a multi-channel read head that generates analog waveforms to create an image of an unknown character. After digitizing and rectifying these waveforms, the system applies threshold values to produce a binary bit map. The start and end of the character are detected through specific patterns in the binary data, allowing for precise character recognition.
