ABSTRACT:
In a method for forming an image transformation matrix for an arbitrarily shaped image segment of a digital image with a computer, a prescribable scan sequence is determined for the picture elements of an image segment of the digital image, a covariance matrix for the picture elements is determined on the basis of this scan sequence. An image transformation matrix is derived from the covariance matrix on the basis of the eigenvectors of the covariance matrix.
