TH65504A - Implicit weighing of the reference image in the image decoder. - Google Patents

Abstract

DC60 (19/12/46) Image Decoder Image encoder And corresponding methods for processing the data. Video signal for image blocks With both reference image pointers to predict the image block. Was revealed which used Implicit Weighing Benefits of Reference Images Add image compression Where the decoder is composed of a weight factor unit implicit reference image For determining the weighing factor corresponding to each reference image index. The coding machine consists of Weighing factor designer Implicit reference image For designing the weighing factor corresponding to each reference image index and the method for decoding it consists of receiving a reference image pointer. The data is matched to the image block, determining the weighing factor in response to the relative position of the image block and the reference image displayed by each reference image index. Restoring reference images for each index. Compensation for restored reference image motion And the multiplication of the reference image compensating motion by Matching weighing factors To form a reference image, compensate for the weighted movement Image decoder Image encoder And corresponding methods for processing the data. Signal for block picture With both reference image pointers to predict the image block. Was revealed which used Benefits of Implicit Weighing of Reference Images, Increasing the Compression Where the decoder is composed of a weight factor unit implicit reference image For determining the weighing factor corresponding to each reference image index. The coding machine consists of Weighing factor designer Implicit reference image For designing weighing factors that are synchronized with each reference image index and the method for decoding it consists of obtaining a reference image pointer to the data which is synchronized with the image block, determining the weighing factor at Responds to the relative position of the block and reference image displayed by each reference image index. Restoring reference images for each index. Compensation for restored reference image motion And the multiplication of the reference image compensating motion by Matching weighing factors To form a reference image, compensate for the weighted movement

Claims (2)

1. Video decoder for decoding video signal data for block pictures with First and second reference image pointer to predict image blocks. The decoder consists of a reference image weighing factor unit (280) responding to the relative position between the first and second image block and reference image. Weighing factor unit, reference image with Output for Determine the implicit reference image factor Which corresponds to each of the first and second reference pointer, respectively 2. Image decoder as set forth in the tagged disclaimer:
