IMAGE ENCODING AND DECODING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240187611 titled 'IMAGE ENCODING AND DECODING METHOD AND APPARATUS
Simplified Explanation
The patent application describes a method and apparatus for image encoding and decoding, involving reading sub-images from memory, encoding them, and reconstructing the images.
- Reading a sub-image from off-chip memory and storing it in on-chip memory.
- Encoding the base layer of the sub-image to obtain a bitstream and a reconstructed image.
- Writing the reconstructed image back into memory.
- Reading the reconstructed image and the sub-image from memory.
- Encoding an enhancement layer of the sub-image to obtain a bitstream and a second reconstructed image.
Potential Applications
This technology could be used in video streaming, image compression, and virtual reality applications.
Problems Solved
This technology solves the problem of efficiently encoding and decoding images while minimizing memory usage.
Benefits
The benefits of this technology include improved image quality, reduced memory requirements, and faster processing speeds.
Potential Commercial Applications
Potential commercial applications of this technology include video streaming services, image editing software, and virtual reality platforms.
Possible Prior Art
Prior art may include existing image encoding and decoding methods, such as JPEG and MPEG standards.
== What are the potential limitations of this technology? One potential limitation of this technology could be the complexity of the encoding and decoding process, which may require specialized hardware or software to implement effectively.
== How does this technology compare to existing image encoding and decoding methods? This technology offers the advantage of storing sub-images in on-chip memory, which can improve processing speeds and reduce memory usage compared to traditional off-chip memory storage methods.
Original Abstract Submitted
this application provides an image encoding and decoding method and apparatus. the method may include: reading a first sub-image of a first frame of image from a first memory, and storing the first sub-image into a second memory, where the first memory is an off-chip memory, and the second memory is an on-chip memory; encoding a base layer of the first sub-image based on the first sub-image, to obtain a bitstream of the base layer of the first sub-image and a first reconstructed image; writing the first reconstructed image into the second memory; reading the first reconstructed image and the first sub-image from the second memory; and encoding a first enhancement layer of the first sub-image based on the first reconstructed image and the first sub-image, to obtain a bitstream of the first enhancement layer of the first sub-image and a second reconstructed image.
