Object recognition method and apparatus

An object recognition apparatus comprising:

• an interface for receiving address event representation (AER) data from an AER sensor;
• a processor configured to perform operations of:
• obtaining, from the AER sensor via the interface, AER data of a to-be-recognized object, wherein the AER data comprises a plurality of AER events of the to-be-recognized object, and each AER event comprises a timestamp and address information;
• extracting a plurality of feature maps of the AER data, wherein each feature map comprises partial spatial information and partial temporal information of the to-be-recognized object, and the partial spatial information and the partial temporal information are obtained based on the timestamp and the address information of each AER event;
• and
• recognizing the to-be-recognized object based on the plurality of feature maps of the AER data,
• wherein the operation of extracting the plurality of feature comprises:
• processing address information of the plurality of AER events by using a plurality of filters, to obtain a plurality of first feature maps;
• and
• attenuating, as a function of time, feature values in the plurality of first feature maps based on timestamps of the plurality of AER events, to obtain the plurality of feature maps of the AER data.
