Predicting corresponding region in a third view using discrete epipolar lines

Abstract : The discrete epipolar line, a discrete version of the epipolar line, is recently proposed to give geometric relationships between pixels in two different views so that we can directly deal with pixels in digital images. A method is then proposed to determine the discrete epipolar line providing that fully calibrated images are available. This paper deals with weakly calibrated digital images and proposes a method for determining the discrete epipolar line using only weakly calibrated images. This paper also deepens the work further, presenting a method for identifying the corresponding region in a third view from a given pair of corresponding pixels in two views.
