Title: Geert F G Depovere: Innovator in Watermark Detection Technology

Introduction

Geert F G Depovere is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of watermark detection, holding a total of 3 patents. His innovative methods have advanced the way watermarks are detected in various information signals.

Latest Patents

One of Geert's latest patents involves a sophisticated watermark detection technique. In this method, an input image is distorted to reduce its correlation with a watermark. The distorted image is then subtracted from the input image to create a preprocessed image. If the correlation between this preprocessed image and the watermark is sufficient, the watermark can be detected in the original input image. The distortion can take various forms, including spatially-variant distortions such as stretching, shrinking, shearing, or rotation. Additionally, non-linear transformations or filtering methods, such as median, local minimum, or local maximum filtering, may also be applied.

Another patent focuses on a method and arrangement for detecting a watermark in an information signal. This method computes the correlation of the watermark with the information signal, such as an image, across multiple positions. It detects whether any of the correlation values exceed a predetermined threshold. The detection process includes determining the standard deviation of the correlation values and setting the threshold based on a desired false alarm rate.
