Method for updating data, electronic device, and storage medium

An electronic device, comprising:

• a processor;
• and
• a memory configured to store an instruction executable by the processor,
• wherein the processor is configured:
• acquire a first image of a target object, and acquire a first image feature of the first image;
• acquire a second image feature from a local face database;
• perform similarity comparison between the first image feature and the second image feature to obtain a comparison result;
• acquire, responsive to that the comparison result is greater than a feature update threshold, a difference feature between the first image feature and the second image feature, and to take the difference feature as a dynamic update feature;
• and
• adaptively update the second image feature according to the dynamic update feature to obtain updated feature data of the target object.

A non-transitory computer-readable storage medium, having stored thereon a computer program instruction that, when executed by a processor, causes the processor to:

• acquire a first image of a target object, and acquire a first image feature of the first image;
• acquire a second image feature from a local face database;
• perform similarity comparison between the first image feature and the second image feature to obtain a comparison result:
• acquire, responsive to that the comparison result is greater than a feature update threshold, a difference feature between the first image feature and the second image feature, and to take the difference feature as a dynamic update feature:
• and
• adaptively update the second image feature according to the dynamic update feature to obtain updated feature data of the target object.
