Title:
DATA COMPRESSION METHOD FOR ELECTROENCEPHALOGRAM DATA, CHIP, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/198150
Kind Code:
A1
Abstract:
The present application relates to the technical field of computers, and relates to a data compression method for electroencephalogram data, a chip, a device, and a storage medium. The method comprises: obtaining target electroencephalogram data (201); determining, from data ranges, a target data range to which the target electroencephalogram data belongs (202), the data ranges being obtained by dividing a maximum data range of electroencephalogram data; determining a target data compression rate corresponding to the target data range (203); and using the target data compression rate to compress the target electroencephalogram data to obtain compressed electroencephalogram data, so as to store the compressed electroencephalogram data (204). The problem that the amount of data stored in a brain-computer interface device is large due to the fact that electroencephalogram data changes slowly and the brain-computer interface device generally needs to collect the electroencephalogram data for a long time can be solved; since the target electroencephalogram data is first compressed and then the electroencephalogram data is stored, the size of the stored electroencephalogram data can be reduced, thereby reducing the amount of data stored in the brain-computer interface device and saving the storage space.
