Abstract
Official abstract text for this publication.
Coding techniques for a video image compression system involve improving an image quality of a sequence of two or more bi-directionally predicted intermediate frames, where each of the frames includes multiple pixels. One method involves determining a brightness value of at least one pixel of each bi-directionally predicted intermediate frame in the sequence as an equal average of brightness values of pixels in non-bidirectionally predicted frames bracketing the sequence of bi-directionally predicted intermediate frames. The brightness values of the pixels in at least one of the non-bidirectionally predicted frames is converted from a non-linear representation.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for pixel value interpolation of a current frame in an image system, the method comprising: applying a motion compensation filter for fractional motion vector displacement on integer pixel points of a reference frame to determine a value for a fractional point, the motion compensation filter including a positive lobe between two negative lobes, wherein the reference frame is further distant than another referenceable frame in display order to the…
