In computer vision, Depth Image Based Rendering (DIBR) is a crucial technique for creating stereoscopic images by generating novel viewpoints and corresponding depth images. DIBR technology finds extensive applications across various domains including 3D cinema, virtual reality, augmented reality, and video conferencing systems. Additionally, DIBR serves important functions in 3D reconstruction and object recognition tasks. The core implementation typically involves warping algorithms that transform original color images using depth maps to create new perspective views, often utilizing z-buffering techniques for proper occlusion handling. Key computational steps include depth-based pixel projection, hole filling algorithms for disoccluded regions, and view interpolation methods. Consequently, DIBR has become an indispensable component in the computer vision field, with common implementations involving OpenCV or custom shaders for real-time rendering applications.
