Title: Ralph N Crabtree: Innovator in Object Tracking Technology

Introduction

Ralph N Crabtree is a notable inventor based in Atlanta, GA, with a focus on advancements in object tracking technology. He holds a total of 7 patents, showcasing his contributions to the field of video analysis and movement tracking.

Latest Patents

Crabtree's latest patents include a system and method for tracking the movement of objects in a scene using correspondence graphs. This innovative approach utilizes two types of graphs: an object correspondence graph and a track correspondence graph. The object correspondence graph consists of nodes representing region clusters in a scene, which are hypotheses of objects to be tracked. The track correspondence graph, on the other hand, comprises nodes corresponding to tracks in the first graph, representing the path of an object through the scene. This dual-graph system accumulates tracking information for various objects, such as people, enhancing the accuracy of movement tracking in video streams.

Another significant patent by Crabtree is a system and method for tracking movement of objects through a scene. This method generates a background image to compare with video frames, identifying regions that potentially represent objects. By forming region clusters and evaluating them against object model information, Crabtree's system generates confidence values for each cluster, determining their likelihood of representing trackable objects. This innovative technology constructs tracks of objects over time based on correspondences between region clusters in consecutive video frames.
