Cut-Decoding and 4-Sets-Cut-Decoding algorithms are proposed elsewhere. They give improvement in decoding processes of Random Codes Based on Quasigroups (RCBQ). These codes are cryptcodes, so they provide a correction of certain amount of errors in the input data and an information security, all built in one algorithm. Performances of these codes for decoding images transmitted through a binary-symmetric channel are investigated elsewhere. In this paper, we consider a transmission of images through Gaussian channel and propose a filter for enhancing the quality of images decoded with Cut-Decoding and 4-Sets-Cut-Decoding algorithms. In the decoding process of these codes, three types of errors appear: more-candidate-error, null-error and undetectederror. With the proposed filter we can visually enhance only pixels damaged by first two kinds of errors.
