We have proposed a novel method for free viewpoint generation in which "walk-through" view experience can be realized by using multiple local ray-spaces representation. In this paper, we extend our approach to utilize a zenith camera as well as horizontal camera array. Simulation result shows that we can successfully navigate the viewpoint vertically and horizontally in 3D space.

The proposed method extracts two image features that reflect the significance of blocking and flickering artifacts and estimates the subjective quality by weighted sum of the image features. Computer simulations show that the proposed method can estimate subjective quality at a correlation coefficient of 0.754.
