Abstract

A method for pre-processing block-based digital data that pre-processes each digital pixel based on a respective data filter arrangement or data filter matrix for a respective data pixel within at least one data block and selects, constructs, and/or supplies the data filter arrangements or data filter matrices. The method is based on operations of data shifting and/or register shifting only.
