With a total of 4 patents, Zettler's work has had a lasting impact on how images and videos are compressed and represented.

Latest Patents

Zettler's latest patents include a method and apparatus for representing an image by iteratively filtering. This invention involves an apparatus for decompressing an image that has been compressed by an image compression system. The process includes repetitively filtering the image in one direction to produce a series of sub-images, which are then filtered in a second direction to create an image representation with varying spatial frequency content. The decompression apparatus effectively reverses the filtering process to recover the original image. Another significant patent is a method and apparatus for coding motion pictures. This invention discloses a method for compressing motion pictures by dividing the frames into adjacent groups and treating each group as a three-dimensional image. The three-dimensional image is filtered using a three-dimensional FIR filter to generate component images that are quantized more efficiently. The quantization degree is influenced by the spatial frequencies represented by the component images, ensuring high-quality motion picture output.
