This thesis present a method which simultaneously manipulates perspective
of a binocular image using space-controls similar to those used by illustrators.
A user annotates one image of a input images pair by marking
some constraints including planar regions, straight lines, and vanishing
points. Then, our method computes the associated warp for both images
based on those constraints sketched by users and other stereoscopic constraints
derived by a sparse feature correspondences. Our system deforms
the input stereoscopic images such that planar regions transform according
to a homography, straight lines remain unbent, vanishing points cross at the
desire position, and the mapping of corresponding features is visually comfortable.
Because of lack of 3D scene geometry, the result is not necessarily
an accurate perspective projection of the scene, but it is often visually plausible.
