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 18471371 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 the 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 for 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:
- Image and video decoding systems
- Multimedia compression and decompression algorithms
- Video streaming and broadcasting platforms
- Digital image processing software
Problems solved by this technology:
- Improving the accuracy and quality of image decoding
- Reducing artifacts and distortions in decoded images
- Enhancing the efficiency of compression and decompression algorithms
Benefits of this technology:
- Higher fidelity and clarity in decoded images
- Improved visual experience for users
- More efficient use of network bandwidth and storage space
- Enhanced performance of image and video processing applications
Original Abstract Submitted
Provided is an image decoding method including: generating an intra prediction value of a current sample based on a position of the current sample in a current block and an intra prediction mode of the current block; determining a sample value of at least one filtering reference sample to be filtered and a first weight with respect to the filtering reference sample and a second weight with respect to the intra prediction value of the current sample; generating a filtered prediction sample value of the current sample based on the determined sample value of the filtering reference sample to be filtered, the intra prediction value of the current sample, the first weight with respect to the filtering reference sample, and the second weight with respect to the intra prediction value of the current sample; and generating a prediction block of the current block including the filtered prediction sample value.
