Title: Siegfried Schweidler: Innovator in Image Processing Technologies
Introduction
Siegfried Schweidler is a notable inventor based in Gehrden, Germany. He has made significant contributions to the field of image processing, holding a total of 10 patents. His work focuses on methods and apparatuses that enhance the quality and clarity of images.
Latest Patents
One of Schweidler's latest patents is a method and apparatus for determining a sharpness metric of an image. This innovative method allows for the objective and efficient measurement, visualization, and evaluation of image quality in terms of sharpness. It involves performing edge detection to generate gradients for the pixels of the image, determining a contrast metric, and classifying pixels into groups based on calculated thresholds. The sharpness metric is then derived from the relationships between the amounts of pixels in these groups.
Another significant patent by Schweidler is related to the deblurring of an image from a sequence of images. This method includes a motion estimation stage that assesses the motion of the image pixels. It also features a point spread function modeling stage that uses motion estimates to model point spread functions for the pixels. A deconvolution stage is employed to derive a deblurred estimate of the image, with a feedback loop that iteratively improves the motion estimates until convergence is achieved.
Career Highlights
Throughout his career, Schweidler has worked with prominent companies, including Thomson Licensing and Thomson Licensing S.A. His expertise in image processing has positioned him as a key figure in the development of advanced imaging technologies.
