IMAGE ENCODING AND DECODING METHOD AND APPARATUS GENERATING AN ANGULAR INTRA PREDICTION MODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18471381 titled 'IMAGE ENCODING AND DECODING METHOD AND APPARATUS GENERATING AN ANGULAR INTRA PREDICTION MODE
Simplified Explanation
The patent application describes a method for decoding images. Here is a simplified explanation of the abstract:
- The method involves generating an intra prediction value for a current sample in a current block based on the position of the sample and the intra prediction mode of the block.
- It determines a sample value for at least one filtering reference sample to be filtered, along with a first weight for the filtering reference sample and a second weight for the intra prediction value of the current sample.
- A filtered prediction sample value for the current sample is generated using the determined sample value, the intra prediction value, the first weight, and the second weight.
- Finally, a prediction block of the current block is generated, including the filtered prediction sample value.
Potential applications of this technology:
- Video compression and encoding: The method can be used in video codecs to improve the efficiency of compression and encoding processes, resulting in smaller file sizes and better video quality.
- Image processing: The method can be applied in various image processing applications, such as denoising, image enhancement, and image restoration, to improve the quality of processed images.
Problems solved by this technology:
- Improved image quality: By generating a filtered prediction sample value based on the determined sample value and the intra prediction value, the method can enhance the accuracy and quality of decoded images.
- Efficient compression: The method allows for better prediction of sample values, leading to more efficient compression algorithms and reduced file sizes.
Benefits of this technology:
- Higher compression efficiency: By generating accurate prediction sample values, the method can improve the compression efficiency of image and video codecs, resulting in smaller file sizes.
- Enhanced image quality: The use of filtering reference samples and weights can improve the quality of decoded images, reducing artifacts and noise.
- Versatile image processing: The method can be applied in various image processing applications, providing flexibility and versatility in enhancing and restoring images.
