  • Method and apparatus for determining image similarity and position
    Patent number: 6154566
    Abstract: An apparatus for determining a similarity between model image and inputted image, which is robust even if the background of said inputted image is partly changed. The similarity is calculated from an edge direction of an inputted image, an edge direction of a model image and a weight related to the model image. The calculating steps used are (1) calculating an edge direction difference between an inputted model image and a model image, (2) calculating weights related to model image, (3) multiplying edge directions and weights, (4) calculating a sum of the multiplication, (5) calculating a sum of the weights, and (6) calculating a similarity by dividing the sum of the multiplication by the sum of the weights.
