摘要
it is a procedure to review the convergence in the fractal bildcodierung is proposed. this is a material digitalized image into a number of rangeblu00f6cken (ri, ri + 1) and in a number of domainblu00f6cken (dj), dk). each rangeblock is similar to domainblock.it will, if necessary, a transformation of a domainblocks made to the domainblock on a rangeblock themselves. the assignment of the domainblock to rangeblock including the transformation parameters represents the fractal code for the image. to check the convergence of the fractal codes, a reduced transformation matrix is developed.the betragsgru00f6u00dfte eigenvalue of the transformation matrix is an approximation. the whole procedure can be executed hierarchically. in a first nu00e4herungsschritt is at least the zeilensummennorm each row of the reduced transformation matrix were reviewed. further steps are summarized further lines to higher dimensional quadratic matrices.of these, the betragsgru00f6u00dften eigenvalues to be konvergenzkontrolle.
