PREDICTION IMAGE GENERATION DEVICE, MOVING IMAGE DECODING DEVICE, AND MOVING IMAGE CODING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18231898 titled 'PREDICTION IMAGE GENERATION DEVICE, MOVING IMAGE DECODING DEVICE, AND MOVING IMAGE CODING DEVICE
Simplified Explanation
The patent application describes a method to improve coding efficiency in image processing.
- A motion compensation filter unit is used to process an image that has been modified by applying a motion vector to a reference image.
- The motion compensation filter unit applies filter coefficients, denoted as mcFilter[i][k], to the motion vector applied image.
- The filter coefficients mcFilter[i][k] are calculated using other filter coefficients mcFilter[p][k] and mcFilter[q][k], where p and q are not equal to i.
Original Abstract Submitted
Coding efficiency is improved. A motion compensation filter unit acts on a motion vector applied image obtained by acting a motion vector on a reference image. The motion compensation filter unit causes filter coefficients mcFilter[i][k] designated by a phase i and a filter coefficient position k to act on the motion vector applied image. The filter coefficients mcFilter[i][k] includes filter coefficients calculated by using filter coefficients mcFilter[p][k] (p≠i) and filter coefficients mcFilter[q][k] (q≠i).
