The blockness and ringing are the two main types of artifacts occurring as a result of the use of block image compression and video coding algorithms for a high compression ratio. Today, most of applied deblocking and deringing algorithms are time-consuming and can not be used for devices which perfect coding/decoding in the real time mode. The adaptive deblocking post-processing algorithm is offered in this paper. The algorithm allows one to underline textures without changing them and, also, eliminates ringing artifacts on the decoded images. The offered algorithms decrease disadvantages of image coding and give good contours and real textures keeping for real edges in decoded images. Moreover, the developed methods are not time-consuming and may be integrated in any type of processors. Preliminary experiments have shown that for $352\times 288$ images, the working time was about 0.31 ms, and with a special optimization these algorithms may really work in real time (25–30 frames per s).
