Abstract
The proposed technology provides methods, devices and computer programs for performing data error detection and correction. It is provided a method for performing data error detection and correction. The method comprises the step S1 of providing multiple Mojette transform projections (pi,q,) obtained by applying an encoding Mojette transform on an input, or original, block of data elements or values. The method also comprises decoding S2 the multiple Mojette transform projections to form a reconstructed block of data elements or values. The method also comprises investigating S3 whether any of the decoded Mojette transform projections comprises at least one bin≠0 following generation of the reconstructed block, thus providing an indication that a data error has been detected in the reconstructed block. The method also comprises determining S4, if at least one bin≠0, a corrected reconstructed block of data elements or values based on the decoded Mojette transform projections. The proposed technology also provides devices and computer programs implementing the method.
