  • Patent number: 11250588
    Abstract: The present disclosure discloses a method and apparatus for filtering glints. The method includes that: a first image and a reference image matched with the first image are acquired, and first-type glints are displayed in the first image; second-type glints in the first image are determined according to the reference image, and the second-type glints are glints obtained by estimating glints in the first image on the basis of the reference image; a matching result of the first-type glints and the second-type glints is determined according to first positions of the first-type glints and second positions of the second-type glints; and the first-type glints are filtered according to the matching result.
