IMAGE CODING METHOD ON BASIS OF SECONDARY TRANSFORM AND DEVICE THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18100781 titled 'IMAGE CODING METHOD ON BASIS OF SECONDARY TRANSFORM AND DEVICE THEREFOR
Simplified Explanation
The patent application describes a method for decoding image information using a decoding device. Here are the key points:
- The method involves decoding a non-separable secondary transform (NSST) index from a bitstream if NSST is applied to a specific block in the image.
- Information related to transform coefficients for the target block is then decoded from the bitstream based on the decoded NSST index.
- The transform coefficients for the target block are derived using the decoded information related to the transform coefficients.
- It is important to note that the NSST index is decoded before the information related to the transform coefficients for the target block.
Potential applications of this technology:
- Image and video compression: The method can be used in compression algorithms to efficiently decode image information and improve the compression ratio.
- Image and video processing: The method can be applied in various image and video processing tasks, such as denoising, enhancement, and restoration.
Problems solved by this technology:
- Efficient decoding: The method provides a way to decode image information in a more efficient manner, reducing computational complexity and improving decoding speed.
- Improved compression: By accurately decoding transform coefficients, the method can enhance the compression ratio, allowing for more efficient storage and transmission of images and videos.
Benefits of this technology:
- Faster decoding: The method allows for faster decoding of image information, which can be beneficial in real-time applications or scenarios where quick processing is required.
- Higher compression ratio: By accurately decoding transform coefficients, the method can improve the compression ratio, resulting in reduced file sizes and bandwidth requirements.
- Improved image quality: The method ensures accurate decoding of transform coefficients, leading to better image quality after compression and decompression processes.
Original Abstract Submitted
An image information decoding method performed by means of a decoding device according to the present invention comprises the steps of: decoding a non-separable secondary transform (NSST) index from a bitstream if NSST is applied to a target block; decoding information relating to transform coefficients with respect to the target block from the bitstream on the basis of the decoded NSST index; and deriving the transform coefficients with respect to the target block on the basis of the decoded information relating to the transform coefficients, wherein the NSST index is decoded prior to the information relating to the transform coefficients with respect to the target block.
