Bidirectional bilateral depth generation based on belief mapping

二维视频到三维视频转化技术中,深度图像生成至关重要。介绍一种基于置信度映射的半自动深度产生算法,利用关键帧深度信息和改进的双向双边滤波算法产生其他帧深度信息。此算法利用置信度映射技术减轻未被遮挡区域的模糊程度。

Depth generation is very important in 2D to 3D video conversion.This paper presents a semi-automatic depth generation method based on belief mapping.The initial depth information is used for key frames,and for other frames the improved bi-direction bilateral filtering algorithm is used.Such process involves belief mapping which contains confidence of estimated depth of both directions to alleviate blurring for de-occluded areas.
