Title: Gregory T. Koeln: Innovator in Digital Imagery Processing

Introduction

Gregory T. Koeln is a notable inventor based in Germantown, MD (US). He has made significant contributions to the field of digital imagery processing, particularly through his innovative patent that enhances the analysis of spatial data.

Latest Patents

Koeln holds a patent for a "Process and apparatus for cross-correlating digital imagery." This invention involves a system and method for processing high-resolution data from maps, aerial photographs, and other spatial data alongside low-resolution data. The goal is to accurately identify changes in the studied areas. The system relies on a vectorized database classified according to topographical features. Change is defined by a Z-statistic, which is calculated using a two-pass cross-correlation technique. This technique compares pixel brightnesses to a mean brightness for the typical topographical class and to a standard deviation for that class. The normalized difference values are accumulated across different bands, scaled, and compared to a threshold that defines high, medium, and low change values. Ultimately, a map is automatically produced to illustrate areas of significant change.
