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 18471390 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 based on its position in a current block and the intra prediction mode of the block.
- It determines a sample value of 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 of the current sample is generated using the determined sample value of the filtering reference sample, the intra prediction value of the current sample, the first weight for the filtering reference sample, and the second weight for the intra prediction value.
- Finally, a prediction block of the current block is generated, which includes the filtered prediction sample value.
Potential applications of this technology:
- Video compression and encoding: The image decoding method can be used in video compression algorithms to improve the efficiency of encoding and decoding processes.
- Image processing: The method can be applied in various image processing applications, such as image enhancement, restoration, and filtering.
Problems solved by this technology:
- Improved image quality: By generating a filtered prediction sample value based on the determined weights, the method can enhance the accuracy and quality of decoded images.
- Efficient decoding: The method optimizes the decoding process by utilizing intra prediction values and filtering reference samples, resulting in faster and more efficient image decoding.
Benefits of this technology:
- Enhanced image compression: The method improves the compression efficiency by generating accurate prediction sample values, leading to reduced file sizes for encoded images or videos.
- Improved image quality: By incorporating filtering reference samples and weights, the method enhances the visual quality of decoded images, reducing artifacts and distortions.
