Title: G Finn Wredenhagen: Innovator in Video Signal Processing
Introduction
G Finn Wredenhagen is a notable inventor based in Toronto, Canada. She has made significant contributions to the field of video signal processing, holding a total of 8 patents. Her work focuses on innovative methods for detecting and reducing noise in video signals, showcasing her expertise in this specialized area.
Latest Patents
Wredenhagen's latest patents include a "System and method for detecting a non-video source in video signals." This invention involves a video sequence that may include a modality corresponding with an embedded pattern. At least one state machine detects the modality in accordance with difference signals. A signal generator generates the difference signals responsive to decision windows that define regions of interest in the video sequence. The modality may correspond with an embedded film source or other pattern types in the video sequence. The state machine discerns the presence of the embedded film source patterns notwithstanding the presence of the static patterns.
Another significant patent is the "System and method for reducing noise in images." This method provides a way to select a filter for interpolating a target pixel to reduce noise in an image. The method comprises comparing a plurality of pixels along a predetermined contour with a plurality of predefined patterns. The patterns represent visually significant patterns possible along said contour. A filter is selected from a predefined set of filters in accordance with the results of the comparison.
