Among all the feature matching algorithms, SURF is famous for its computation efficiency in lots of practical applications. For recently popular stereoscopic videos, sparse feature matching, in which SURF is usually adopted, is the pre-processing of adjusting the 3D effect. However, significant improvement still can be made for SURF in stereo images. In this paper, a new two-layer feature descriptor...
In this paper, an efficient depth image based view rendering method for high quality multiview virtual images synthesis is proposed, which utilizes two color images with their associated depth maps. The proposed method consists of four main steps. The first step is virtual camera parameters design by using shift-sensor camera model to avoid the keystone distortion. Secondly, the mixed color pixels...
Recent computer vision technology has made great progress in 3DTV industry. The advent of 3DTV to the home raises a number of challenges beyond the basic display of an available stereo pair. One of them is the production of 3D augmented contents. To present virtual objects over the real world, the existing method is offline processing in postproduction. It is a difficult and expensive work since flexible...
An asymmetric edge adaptive filter (AEAF) is proposed in this paper to partially solve two puzzles in 3DTV, i.e. depth generation and hole filling. Different from other similar processing methods, one time of AEAF operation can simultaneously achieve the effect of edge correction and pre-processing of the depth maps. Thus the computing complexity can be greatly reduced. On the one hand, based on the...
