Abstract
Official abstract text for this publication.
A method and device form a prediction value. A prediction direction is locally described by nonlinear trajectories. The prediction direction can be used in forming a prediction value to achieve a more accurate prediction determination. The method and device can be used in image compression or image-sequence compression.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for forming a prediction value for a first image value of a first pixel of an image on the basis of second image values of respective reconstructed pixels of the image, the method comprising: forming at least two trajectories, each trajectory having a third image value for points along the trajectory, each trajectory having a shape that is not a straight line; assigning a second image value to each third image value and thereby each trajecto…
