The present invention relates to hidden in a kind of surface by edge limited and contained point IP error value V [IP] is associated with which, including at least one point on interpolation procedure the INT newly surface value V ' [IP] from interpolation point IP TP, RP, BP, the step PDC that the projection step PRO limited in LP is projected in the edges IP to the surface of orthogonal direction interpolation point determines first distance TD, RD, BD, the interpolation point IP and above-mentioned interpolation T P limited between LD, RP, BP, LP, each of the calculating of step SDC and the direction of first distance, the summation is known as secondary range VS, HS. Interpolations steps INT according to the present invention can determine the point IP of the interpolation of new value V ' [IP] from these values V [TP], V [RP], V [BP], V [LP] and each interpolated point TP, RP, BP, LP W [TP] weight by weight, W [RP], W [BP], the step PCC distances calculated in W [LP], secondly according to each main distance. Using: error concealing (MPEG images etc.)
