Image generation method and apparatus, electronic device, and storage medium

An image generation apparatus, comprising a memory for storing instructions and at least one processor configured to execute the instructions to:

• obtain a real biometric image of a target object;
• apply a plurality of image transformations to the real biometric image to obtain a plurality of transformed images, each transformed image retaining an identify feature of the target object;
• extract a feature from each transformed images to obtain a plurality of image features;
• generate a general feature of the target object based on the plurality of image features;
• extract a plurality of image transformation features from the plurality of image features, each image transformation features being irrelevant to the identity feature of the target object;
• fuse the general feature with the plurality of image transformation features to create a fused feature;
• and
• generate a simulated biometric image of the target object based on the fused feature.

A non-transitory storage medium for storing computer readable instructions, the computer readable instructions, when executed by a processor in a device, causing the device to:

• obtain a real biometric image of a target object;
• apply a plurality of image transformations to the real biometric image to obtain a plurality of transformed images, each transformed image retaining an identify feature of the target object;
• extract a feature from each transformed images to obtain a plurality of image features;
• generate a general feature of the target object based on the plurality of image features;
• extract a plurality of image transformation features from the plurality of image features, each image transformation features being irrelevant to the identity feature of the target object;
• fuse the general feature with the plurality of image transformation features to create a fused feature;
• and
• generate a simulated biometric image of the target object based on the fused feature.
