Title:
IMAGE ENCODING, DECODING, RECONSTRUCTION, AND ANALYSIS METHODS, SYSTEM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/005740
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are image encoding, decoding, reconstruction, and analysis methods, a system, and an electronic device, the image encoding method comprising: acquiring an original image; extracting high-level semantic information of the original image, the high-level semantic information being used for an image analysis task of the original image; extracting a low-level feature of the original image, the low-level feature and the high-level semantic information being used for an image reconstruction task of the original image; encoding the high-level semantic information to generate a first code stream; and encoding the low-level feature to generate a second code stream. In the embodiments of the present application, an encoding scheme is used for fusing user-vision-oriented image reconstruction tasks and machine-vision-oriented image analysis tasks.
