Filter->de- now started. I plane it as de-disarray recorded videosignal which "mechanicaly" damaged. I like to make three functions at least:
chroma or RGB shift (vertically, horizontally and chain);
Ver. 0.21 - fixed, reconstructed 2nd pass.
Filter Source code
Ver. 0.2 - fixed BIG BUG set. Now it working.
Ver. 0.1 - added smoothing for vertical and horizontal borders.
Ver. 0.09 - 1st step chroma or RGB shift
