We have applied two-dimensional homography to correct positional errors in the image domain and avoid re-processing the visibility data. Positions of bright (above 15-$σ$) sources, common to MRT and MRC catalogues, are used to set up an over-determined system to solve for the 2-D homography matrix. After correction, the errors are found to be within 10% of the beamwidth for these bright sources and the systematics are eliminated from the images.4 pages, 4 figures, The Low-Frequency Radio Universe, Proceedings of a conference held at NCRA-TIFR, Pune, 8-12 December 2008, ASP Conference Series, Vol. 407, 2009, Eds: D.J.
