IMAGE ENCODING/DECODING METHOD AND DEVICE FOR SIGNALING FILTER INFORMATION ON BASIS OF CHROMA FORMAT, AND METHOD FOR TRANSMITTING BITSTREAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18092826 titled 'IMAGE ENCODING/DECODING METHOD AND DEVICE FOR SIGNALING FILTER INFORMATION ON BASIS OF CHROMA FORMAT, AND METHOD FOR TRANSMITTING BITSTREAM
Simplified Explanation
The patent application describes a method and apparatus for encoding and decoding images. The image decoding method includes determining the chroma array type of the current image, determining an adaptive loop filter (ALF) indicator for the chroma component based on the chroma array type, and performing ALF filtering on the reconstructed image based on the value of the ALF indicator.
- The method determines the type of chroma array used in the current image.
- Based on the chroma array type, the method determines the ALF indicator for the chroma component.
- The ALF filtering is performed on the reconstructed image using the value of the ALF indicator.
- If the chroma array type is a predetermined type, the value of the ALF indicator is predetermined and does not need to be obtained from the bitstream.
- If the chroma array type is not the predetermined type, the value of the ALF indicator is obtained from the bitstream.
Potential applications of this technology:
- Video encoding and decoding systems
- Image processing applications
- Multimedia streaming and compression technologies
Problems solved by this technology:
- Efficient encoding and decoding of images
- Improved image quality and compression efficiency
- Adaptive filtering based on the chroma array type
Benefits of this technology:
- Enhanced image quality with reduced artifacts
- Efficient use of computational resources
- Improved compression efficiency for multimedia applications
Original Abstract Submitted
An image encoding/decoding method and apparatus are provided. An image decoding method performed by an image decoding apparatus may include determining a chroma array type of a current image, determining an adaptive loop filter (ALF) indicator of a chroma component based on the chroma array type, and performing ALF filtering with respect to a reconstructed image based on a value of the ALF indicator. The value of the ALF indicator may be determined to be a predetermined value without being obtained from a bitstream, based on the chroma array type being a predetermined type, and the value of the ALF indicator may be obtained from the bitstream, based on the chroma array type being not the predetermined type.
