A sub-pixel virtual view synthesis method for multiple view synthesis

A sub-pixel virtual view synthesis (SPVVS) method is proposed in this paper. In the proposed method, by promoting the sampling rate of the target virtual view, the sub-pixel information of the corresponding pixel position among multiple input views with sub-pixel displacement can be utilized. A directional adaptive image interpolation is manipulated to generate a high resolution intermediate image, which is then down-sampled to obtain the target synthesized virtual view. The realization procedure of SPVVS is also presented. Experiment result shows significant improvements on subjective quality compared to traditional integer pixel synthesis method. Artifacts such as `hat´ effects can be significantly reduced.
