Patent Images

1. A method for processing gastrointestinal (GI) images, comprising:

  • receiving one or more structured-light images, wherein said one or more structured-light images are captured using an imaging apparatus by projecting structured light onto a body lumen when the imaging apparatus is in the body lumen;

    receiving a regular image, wherein the regular image is captured using the imaging apparatus by projecting non-structured light onto the body lumen when the imaging apparatus is in the body lumen;

    deriving a target distance for a target region in the regular image based on said one or more structured-light images;

    determining a filter based on the target distance and camera parameters associated with the imaging apparatus;

    generating a first processed target region by applying the filter to the target region to improve sharpness of the target region; and

    providing a first processed regular image comprising the first processed target region.
