Latest Patents

David's most recent inventions include a groundbreaking "System and method for finding and classifying patterns in an image with a vision system." This invention utilizes neural net classifiers to enhance the process of finding patterns in images. The system combines a pattern-finding tool with a classifier, which can operate before or after the tool to yield labeled patterns with sub-pixel accuracy. Moreover, it improves performance by informing the pattern finder to focus only on a subset of trained templates when detecting multiple templates. This innovation not only increases the likelihood of accurately identifying shapes but also reduces the search time by cleaning up imaged shapes and eliminating irrelevant pixels.

Another notable patent from David is the "System and method for finding lines in an image with a vision system." This technology identifies line features through a two-step process that computes the gradient field at each image location and detects edge points. By fitting model lines to selected edge points, the system can efficiently find multiple line results through a robust RANSAC-based operation.
