Image processing methods and devices

An image processing device, comprising:

• a processor;
• and
• a memory storing a computer executable instruction, wherein when executed, the executable instruction causes the processor to:
• acquire features of multiple images of a first target object and a standard feature of the first target object;
• determine trusted images of the first target object from the multiple images according to similarities between the features of the multiple images and the standard feature, wherein similarities between features of the trusted images and the standard feature meet a first preset similarity requirement;
• determine similarities between the trusted images of the first target object and trusted images of a second target object to obtain multiple pieces of similarity data;
• and
• determine, according to the multiple pieces of similarity data, whether the first target object is similar to the second target object.

A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by a processor of a device, cause the device perform an image processing method, the method comprising:

• acquiring features of multiple images of a first target object and a standard feature of the first target object;
• determining trusted images of the first target object from the multiple images according to similarities between the features of the multiple images and the standard feature, wherein similarities between features of the trusted images and the standard feature meet a first preset similarity requirement;
• determining similarities between the trusted images of the first target object and trusted images of a second target object to obtain multiple pieces of similarity data;
• and
• determining, according to the multiple pieces of similarity data, whether the first target object is similar to the second target object.
