Edge enhancement of depth based rendered images [PDF]
2014 IEEE International Conference on Image Processing (ICIP), 2014 Depth image based rendering is a well-known technology for the generation of virtual views in between a limited set of views acquired by a cameras array. Intermediate views are rendered by warping image pixels based on their depth. Nonetheless, depth maps are usually imperfect as they need to be estimated through stereo matching algorithms; moreover ...
