Abstract
A method for estimating three-dimensional structure from a two-dimensional image () includes obtaining first and second vanishing points (); comparing image patches () along first and second virtual lines () extending from the first and second vanishing points (), respectively, and through a pixel; generating values for each of the first and second virtual lines () based on the comparison of the image patches (); accumulating the values for each the pixel in the two-dimensional image (); and determining a corner pixel () based on a highest of the accumulated values.
