1. A method for detecting at least one vanishing point from an image, the method comprising the following steps performed by at least one processor:

  • a dividing step for dividing the image into a plurality of patches;

    a first detecting step for detecting each patch'"'"'s local orientations;

    a composing step for composing lines of pencils from which at least one vanishing point is to be computed based on the local orientations detected in said first detecting step; and

    a first computing step for computing at least one vanishing point based on the lines of pencils composed in said composing step.
