METHOD AND DEVICE FOR PERFORMING IMAGE DECODING ON BASIS OF INTRA PREDICTION IN IMAGE CODING SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18091933 titled 'METHOD AND DEVICE FOR PERFORMING IMAGE DECODING ON BASIS OF INTRA PREDICTION IN IMAGE CODING SYSTEM
Simplified Explanation
The abstract describes a method for image decoding using a decoding device. Here are the key points:
- The method involves determining the intra prediction mode of a current block in an image.
- Neighboring samples, including left and upper neighboring samples of the current block, are derived.
- Reference samples for predicting a target sample among the neighboring samples are derived based on the position of the target sample and the prediction angle of the intra prediction mode.
- An interpolation filter is determined for the target sample.
- The prediction sample of the target sample is derived using the interpolation filter and the reference samples.
Potential applications of this technology:
- Video compression and decompression algorithms.
- Image and video processing software.
- Multimedia devices such as cameras, smartphones, and televisions.
Problems solved by this technology:
- Efficient and accurate image decoding.
- Reduction of data size for transmission or storage.
- Improved image and video quality.
Benefits of this technology:
- Faster and more efficient image decoding.
- Reduced storage and bandwidth requirements.
- Enhanced image and video quality.
Original Abstract Submitted
A method by which a decoding device performs image decoding, according to the present invention, comprises the steps of: deriving an intra prediction mode of a current block; deriving neighboring samples including left neighboring samples and upper neighboring samples of the current block; deriving reference samples for prediction of a target sample among the neighboring samples on the basis of the position of the target sample of the current block and the prediction angle of the intra prediction mode; determining an interpolation filter for the target sample; and deriving the prediction sample of the target sample on the basis of the interpolation filter and the reference samples.
