Title: Innovations of Peter M J Rongen
Introduction
Peter M J Rongen is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of digital image processing, particularly in watermarking techniques. With a total of 4 patents to his name, Rongen's work has had a considerable impact on how digital images are manipulated and secured.
Latest Patents
Rongen's latest patents focus on embedding and detecting watermarks in images. One of his patents describes a method where a digital image signal is watermarked by locally changing geometric features of the image. This watermark consists of a pseudo-random, dense subset of image pixels, such as a pattern of lines. The process involves determining a number of significant image pixels that respond strongly to a predetermined processing operation and moving them to the vicinity of the line pattern. This "warping" technique ensures that most significant image pixels are located near the line pattern, allowing for effective watermark detection at the receiver end. Another patent outlines a method for embedding a watermark in an image by modifying the saliency of salient pixels, ensuring that a significant majority of these pixels are located within the vicinity of the line pattern.
