Title: Sevket Derin Babacan: Innovator in Radiance Processing and Light-Field Imaging
Introduction
Sevket Derin Babacan is a notable inventor based in Evanston, IL (US). He has made significant contributions to the fields of radiance processing and light-field imaging, holding a total of 4 patents. His innovative work has implications for various applications in imaging technology.
Latest Patents
One of his latest patents is titled "Radiance processing by demultiplexing in the frequency domain." This method and apparatus involve obtaining a radiance image captured with a lens-based radiance camera. The image includes optically mixed spatial and angular frequency components of light from a scene. The frequency domain demultiplexing module generates multiple parallax views of the scene by performing frequency domain demultiplexing on the radiance image. The method may extract multiple slices at different angular frequencies from a Fourier transform of the radiance image, apply a Fourier transform to each slice to generate intermediate images, and stack these images to form a 3- or 4-dimensional image. An inverse Fourier transform is then applied along angular dimensions to obtain the multiple parallax views, with phase correction performed to determine the centers of the intermediate images.
Another significant patent is "Method and apparatus for block-based compression of light-field images." This invention describes a method for preprocessing light-field images into a format compatible with block-based compression techniques, such as JPEG. The preprocessing module reshapes the angular data in a captured light-field image to prevent blocking artifacts in the final compressed image. This innovation allows for the production of compressed 2D images that contain full light-field information without requiring a specific light-field image viewer.
