Title: Innovations of John W. Woods
Introduction
John W. Woods is a notable inventor based in Clifton Park, NY (US). He has made significant contributions to the field of video coding technology. With a total of 3 patents, Woods has developed innovative methods that enhance the efficiency of motion vector coding.
Latest Patents
One of his latest patents is titled "Method and apparatus for scalable motion vector coding." This invention focuses on a method and apparatus for scalable coding of a motion vector generated during motion estimation. The generated motion vector field is separated into a base layer and an enhancement layer according to pixel accuracies, creating a layered structure for a motion vector. The base layer consists of motion vectors of blocks larger than or equal to a predetermined size, while the enhancement layer includes motion vectors of blocks smaller than that size.
Another significant patent is "Overlapped block motion compression for variable size blocks in the context of MCTF scalable video coders." This invention involves a method, computer program product, and computer system for processing video frames. In this method, a current frame is divided into M blocks, which include at least two differently sized blocks. Each block is classified as either a motion block or an I-BLOCK. Overlapped block motion compensation (OBMC) is performed on each block according to a predetermined scan order, enhancing the overall video processing efficiency.
