Pose-normailzed view synthesis of a symmetric object using a single image

Object recognition under varying pose is a challenging prob-lem, especially when illumination variations are also present.
In this paper, we propose a pose-normalized view synthe-
sis method under varying illuminations for symmetric ob-
jects. For a given non-frontal view of a symmetric object
under non-frontal illumination, the mirror image of the orig-
inal view is equivalent to the view when the object rotates
around the Y -axis by the same angle as the original view
but in the opposite direction, and under opposite illumina-
tion condition in the X direction. Exploiting the bilateral
symmetry of the object, we generate the mirror view of the
object under the same illumination condition as the original
view on a pixel-by-pixel basis. The frontal view under the
same illumination is then easily obtained using view mor-
phing techniques.
