Title: Innovations of John C. Huffman

Introduction

John C. Huffman is a notable inventor based in Windham, NH (US). He has made significant contributions to the field of image and motion picture compression. With a total of 2 patents, his work has advanced the technology used in visual media.

Latest Patents

Huffman’s latest patents include a "Method and apparatus for coding motion pictures" and an "Image compression method and apparatus." The first patent discloses a method for compressing motion pictures by dividing frames into adjacent groups, treating each group as a three-dimensional image. This three-dimensional image is filtered using a three-dimensional FIR filter to generate component images that are efficiently quantized. The quantization degree is influenced by the spatial frequencies of the component images. For motion pictures derived from interlaced scanning devices, specific component images are quantized differently to prevent artifacts. The second patent presents a system for compressing images using a transformation equivalent to expanding the image with a system of wavelets that have finite support.
