互動調整立體圖片之視角

Abstract

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. vii
