Patent Images

1. A method of aligning a plurality of images having common subject matter, each image being encoded as an ordered set of pixels each having at least one associated pixel parameter, the method comprising:

  • a. featurelessly approximating parameters of a projective coordinate transformation that spatially relates, in first and second images, pixels corresponding to common subject matter therebetween;

    b. applying the parameters to the first image to thereby transform it into a processed image, the common subject matter encoded by pixels in the processed image being substantially spatially consistent with the common subject matter encoded by pixels in the second image; and

    c. aligning the images by combining the pixels corresponding to the common subject matter.
