Title: Innovations by Karl Richard Rasche in High Dynamic Range Video and Image Compression
Introduction
Karl Richard Rasche is an accomplished inventor based in Albany, California. He has made significant contributions to the field of video and image compression, particularly focusing on high dynamic range (HDR) technology. With two patents to his name, Rasche's work has the potential to enhance the quality and efficiency of HDR media.
Latest Patents
Rasche's latest patents include innovative methods for lossy compression of high dynamic range video and image files. The first patent describes a process where HDR video can be compressed using inter-frame or intra-frame compression techniques. This method results in multiple encoded macroblocks and associated residual images. The residual images undergo lossy compression by mapping floating point image data values from a light linear space to a perceptually linear space using a non-linear mapping function. This approach ensures that the compression maintains a balance between file size and visual quality.
The second patent focuses on the lossy compression of HDR image files. Similar to the video compression method, this process involves mapping floating point image data values from a light linear space to a perceptually linear space. The floating point discrete cosine transform (DCT) frequency coefficients are determined, quantized, and then compressed. The compression of these quantized coefficients is lossless, allowing for efficient storage without sacrificing image quality.
Career Highlights
