METHOD AND APPARATUS FOR VIDEO INTRA PREDICTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18320199 titled 'METHOD AND APPARATUS FOR VIDEO INTRA PREDICTION
Simplified Explanation
The abstract describes a method for intra prediction of a block in a video picture. Here is a simplified explanation of the abstract:
- The method involves predicting the content of a block in a video picture.
- The intra prediction mode of the block is obtained, which determines the type of prediction to be used.
- If the intra prediction mode is a wide-angle mode, reference samples for the block are filtered.
- Filtered reference samples are then used to generate predicted samples for the block.
Potential applications of this technology:
- Video compression: This method can be used in video compression algorithms to improve the efficiency of encoding and decoding video data.
- Video streaming: By enhancing the prediction of video blocks, this method can help in delivering high-quality video streams over limited bandwidth networks.
Problems solved by this technology:
- Intra prediction is an essential part of video coding, and accurate prediction can significantly improve video compression efficiency.
- Wide-angle modes require specific handling due to their unique characteristics, and this method addresses the challenges associated with such modes.
Benefits of this technology:
- Improved video compression efficiency: By filtering reference samples based on the wide-angle mode, the method can enhance the accuracy of intra prediction, leading to better compression ratios.
- Enhanced video quality: The use of filtered reference samples can result in more accurate predicted samples, resulting in higher visual quality in decoded video frames.
Original Abstract Submitted
A method of intra prediction of a block in a picture of a video is disclosed. The method comprises obtaining an intra prediction mode of the block; determining whether the intra prediction mode of the block is a wide-angle mode; filtering reference samples for the block based, at least in part, upon determining that the intra prediction mode of the block is the wide-angle mode; and generating predicted samples of the block based on filtered reference samples.
