Where transform coding is used, they typically assume the form of one of the basis functions of the coder's transform space.
These artifacts appear in the form of sharp horizontal and vertical edges which are easily spotted by the human eye and produce ringing effects (large coefficients in high frequency sub-bands) in the Fourier-related transform used for transform coding of the residual frames.
