METHOD AND DEVICE FOR SIGNALING INFORMATION ON CHROMA FORMAT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18244764 titled 'METHOD AND DEVICE FOR SIGNALING INFORMATION ON CHROMA FORMAT
Simplified Explanation
The abstract describes an image decoding method performed by a decoding device. Here is a simplified explanation of the abstract:
- The decoding device receives a bitstream that contains prediction information for a current block of an image.
- Based on the prediction information, the device determines the chroma array type for the current block. This is done by considering a separate color plane flag (indicating whether three color components are separately coded) and a chroma format index (indicating the chroma format sampling structure).
- Using the derived chroma array type, the device calculates prediction samples for the current block.
- Finally, the device derives reconstructed samples for the current block based on the prediction samples.
Potential applications of this technology:
- Video decoding: This image decoding method can be used in video codecs to efficiently decode and reconstruct video frames.
- Image processing: The method can be applied in various image processing applications, such as image compression, image enhancement, and image analysis.
Problems solved by this technology:
- Efficient decoding: By deriving the chroma array type and using it to calculate prediction samples, the decoding device can optimize the decoding process and improve efficiency.
- Accurate reconstruction: The method allows for the derivation of reconstructed samples based on the prediction samples, leading to accurate image reconstruction.
Benefits of this technology:
- Improved image quality: By accurately deriving and reconstructing samples, the image quality can be enhanced, resulting in clearer and more detailed images.
- Faster decoding: The optimized decoding process enables faster decoding of images or videos, reducing processing time and improving overall performance.
Original Abstract Submitted
An image decoding method performed by a decoding device according to the present disclosure comprises the steps of: receiving a bitstream including prediction information for a current block; deriving a chroma array type for the current block on the basis of a separate color plane flag indicating whether three color components are separately coded and a chroma format index indicating a chroma format sampling structure for the current block, which are included in the prediction information for the current block; deriving prediction samples for the current block on the basis of the derived chroma array type; and deriving reconstructed samples for the current block on the basis of the prediction samples.
