Method for determining an association between a matrix element of a matrix and a comparison matrix element of a comparison matrix by means of a plurality of correspondence tables, the table fields of which are at least partially written to in a writing process, wherein the matrix is a first image and the comparison matrix is a second image and a matrix element is a pixel in the first image and a comparison matrix element is a pixel in the second image, comprising the following steps of: - dividing the matrix into a plurality of sub-matrices (101,... 104), wherein a correspondence table (300, 301... 304) is associated with each sub-matrix (101,... 104), - carrying out a writing process for the purpose of writing the position of a matrix element of a sub-matrix (101, 102... 104) to a table field of the associated correspondence table (301,... 304), - carrying out a reading process for the purpose of reading the position of a matrix element from a table field of a correspondence table (300, 301... 304) and creating an association between a position of a comparison matrix element and a matrix element, wherein the writing process comprises the following steps of: - determining a feature of a matrix element of a sub-matrix (101,... 104) of the matrix, - determining an access feature from the feature of the matrix element, - determining a table field of the associated correspondence table (300, 301,... 304) from the access feature, - writing the position of the matrix element of the sub-matrix (101,... 104) of the matrix to the determined table field of the associated correspondence table (300, 301,... 304), - dividing the comparison matrix into a plurality of comparison sub-matrices (201,... 204), wherein one of the correspondence tables (301,... 304) is associated with each comparison sub-matrix (201,... 204), and wherein the reading process comprises the following steps of: - determining a feature of a comparison matrix element of a comparison sub-matrix (201,... 204) of the comparison matrix, - determining an access feature from the feature of the comparison matrix element, - determining a table field of the associated correspondence table (301,... 304) by means of the access feature of the comparison matrix element, - reading the stored position of the matrix element from the determined table field of the associated correspondence table (301,... 304), - forming an association between the position of the matrix element, which has been read from the table field of the associated correspondence table (301,... 304), and the current position of the comparison matrix element of the comparison matrix. - dividing the matrix into a plurality of sub-matrices (101,... 104), wherein a correspondence table (300, 301... 304) is associated with each sub-matrix (101,... 104), - carrying out a writing process for the purpose of writing the position of a matrix element of a sub-matrix (101, 102... 104) to a table field of the associated correspondence table (301,... 304), - carrying out a reading process for the purpose of reading the position of a matrix element from a table field of a correspondence table (300, 301... 304) and creating an association between a position of a comparison matrix element and a matrix element, - determining a feature of a matrix element of a sub-matrix (101,... 104) of the matrix, - determining an access feature from the feature of the matrix element, - determining a table field of the associated correspondence table (300, 301,... 304) from the access feature, - writing the position of the matrix element of the sub-matrix (101,... 104) of the matrix to the determined table field of the associated correspondence table (300, 301,... 304), - dividing the comparison matrix into a plurality of comparison sub-matrices (201,... 204), wherein one of the correspondence tables (301,... 304) is associated with each comparison sub-matrix (201,... 204), - determining a feature of a comparison matrix element of a comparison sub-matrix (201,... 204) of the comparison matrix, - determining an access feature from the feature of the comparison matrix element, - determining a table field of the associated correspondence table (301,... 304) by means of the access feature of the comparison matrix element, - reading the stored position of the matrix element from the determined table field of the associated correspondence table (301,... 304), - forming an association between the position of the matrix element, which has been read from the table field of the associated correspondence table (301,... 304), and the current position of the comparison matrix element of the comparison matrix.
