Currently, images make up most of the transmitted information that needs to be stored and processed. The aim of the work is to compare the approaches of restoring the values of transmission vector distorted by group interference, formed on the basis of bit planes, by analyzing the neighborhood of bits on bit plane and calculating the trend of neighboring values. The task of the study includes modeling of data transmission with a vector formed on the basis of bit planes, theoretical study of approaches to distortion recovery and conducting an experiment. As a result of the experimental part, it was found that the method of analyzing the neighborhood of bits on bit plane has high speed, but determines distorted bits worse than the method of calculating the tendency of neighbors. At the same time, both approaches give the result sufficient for visual perception of content part. Artifacts that occur during restoration do not have strong impact on obtaining information about an image
