Abstract

A system and method for region classification of two-dimensional (2D) images for 2D-to-3D conversion of images to create stereoscopic images are provided. The system and method of the present disclosure provides for acquiring a two-dimensional (2D) image (202), identifying a region of the 2D image (204), extracting features from the region (206), classifying the extracted features of the region (208), selecting a conversion mode based on the classification of the identified region, converting the region into a 3D model (210) based on the selected conversion mode, and creating a complementary image by projecting (212) the 3D model onto an image plane different than an image plane of the 2D image (202). A learning component (22) optimizes the classification parameters to achieve minimum classification error of the region using a set of training images (24) and corresponding user annotations.

Description

technical field [0001] The present disclosure relates generally to computer graphics processing and display systems, and more particularly to systems and methods for region classification of two-dimensional (2D) images for 2D to 3D conversion. Background technique [0002] 2D to 3D conversion is the process of converting an existing two-dimensional (2D) movie into a three-dimensional (3D) stereoscopic movie. 3D stereoscopic films reproduce moving images in such a way that the viewer perceives and experiences depth, for example while viewing such films with passive or active 3D glasses. Major film studios have taken a keen interest in converting traditional films to stereoscopic 3D. [0003] Stereoscopic imaging is the process of visually combining at least two images of a scene taken from slightly different viewpoints to create the illusion of three-dimensional depth. This technique relies on the fact that human eyes are separated by a distance and therefore do not see exa...
