ABSTRACT:
A method and apparatus for rendering images with and without radially symmetric distortions is described in which the forward and backward radial distortion rendering processes are decomposed into two stages. One-dimensional elements in one planar dimension (rows or columns) of an input image are rendered to generate an intermediate buffer, and then one-dimensional elements in the other planar dimension (columns or rows) of the intermediate buffer are rendered to generate an output image. Thus, one-dimensional sampling is performed, and interpolation may be performed in one planar dimension, rather than 2-D interpolation. An input row or column may be decimated, if necessary, before row or column interpolation is performed to generate an output row or column.
