Abstract:
A method for verifying an image can include: acquiring a first feature point set of a source image and a second feature point set of a target image; determining a target local feature point pair based on the first feature point set and the second feature point set; determining a mapped point of the first feature point on the target image; determining a distance between a second feature point and the mapped point; acquiring a quantity of reference local feature point pairs; and determining that the target image is an image acquired by copying the source image based on the quantity being greater than a target quantity.
