  • Image database key generation method
    Patent number: 7539354
    Abstract: A method of generating a matching key for an image is disclosed. The matching key is substantially invariant to rotation, scale and translation. The method starts by forming a spatial domain representation of the image that is substantially invariant to translation of the image. Rotation and/or scaling in the spatial domain representation is next transformed into translation to form a transformed image. A representation of the transformed image is then formed that is substantially invariant to translation of the transformed image. The representation of the transformed image is the matching key for the image.

  • Method and apparatus for uniform lineal motion blur estimation using multiple exposures
    Patent number: 6888566
    Abstract: A method and apparatus (9) for estimating the blur parameters of blurred images (g1, g2) are disclosed. The apparatus (9) has one or more image sensors (10) for capturing the blurred images (g1, g2), a plurality of correlators (20, 30) for performing autocorrelation of the blurred image (g1) and cross-correlation between the two images (g1, g2) respectively, and an error function calculator (40) for evaluating an error function over all possible displacements using the results from the correlators (20, 30). The apparatus (9) further includes an extreme locater (50) for finding the displacement with the minimum value for the error function.
