Image processing method and apparatus, and electronic device

An image processing apparatus, comprising:

• a memory storing processor-executable instructions;
• and
• a processor arranged to execute the stored processor-executable instructions to perform operations of:
• obtaining a key frame image that comprises a target object, and obtain a to-be-processed frame image that comprises the target object;
• extracting one or more feature points in the key frame image and one or more feature points in the to-be-processed frame image, respectively;
• determining a matching relationship between each feature point in the key frame image and each feature point in the to-be-processed frame image;
• and
• determining a transformation relationship based on the feature point in the key frame image and a feature point in the to-be-processed frame image that matches the feature point in the key frame image;
• and
• processing the to-be-processed frame image based on the transformation relationship to obtain a target frame image.

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

• obtaining a key frame image that comprises a target object, and obtaining a to-be-processed frame image that comprises the target object;
• extracting one or more feature points in the key frame image and one or more feature points in the to-be-processed frame image, respectively;
• determining a matching relationship between each feature point in the key frame image and each feature point in the to-be-processed frame image;
• determining a transformation relationship based on the feature point in the key frame image and a feature point in the to-be-processed frame image that matches the feature point in the key frame image;
• and
• processing the to-be-processed frame image based on the transformation relationship to obtain a target frame image.
