N2 - Ray-Space interpolation is one of the key technologies to generate arbitrary viewpoint images so as to implement RaySpace based FTV (Free Viewpoint Television) system. Since Ray-Space data is composed of straight lines with different slopes, how to find the direction of the lines is the problem to be solved in Ray-Space interpolation. In this paper, a radon transform based free view generation algorithm in Ray-Space is proposed. First, feature points of epipolar plane image (EPI) are extracted to form a feature EPI (FEPI). Then, Radon Transform is applied to each FEPI to find the possible interpolation direction. Finally, the optimal interpolation direction is determined by an improved block-based matching algorithm. Experimental results show that the virtual view point image generated by the proposed algorithm has much higher quality than that generated by the traditional pixel matching based interpolation (PMI) and block matching based interpolation (BMI).
