Introduction

John E Bruder is an accomplished inventor based in Arlington, MA (US). He has made significant contributions to the field of image processing and transmission technologies. With a total of three patents to his name, Bruder's work focuses on enhancing the efficiency of image data transmission.

Latest Patents

One of Bruder's latest patents is the "Spatially Adaptive Blur Filter." This invention presents a method and apparatus for selectively pre-filtering signal representations of images. It aims to maintain the frame rate of transmission while reducing the number of expected bits needed to transmit selected block portions of an image frame. The pre-filter utilizes the quantizer state value, which represents the expected bits required for each block, along with a weighted energy error value based on the coding method used. The result is a multi-tap filter that adjusts its amplitudes based on these values.

Another notable patent is the "Method and Apparatus for Efficiently Transmitting Forced Updates." This invention focuses on selecting blocks for intraframe encoding to avoid unnecessary intraframe encoding of blocks that have not diverged. By calculating inter-energy and intra-energy values, the method determines the most efficient encoding technique to use. If the intra-energy is less than the inter-energy, the block is transmitted using intraframe encoding. Otherwise, it may be transmitted using interframe encoding or not transmitted at all.
