IBR subjective evaluation. (a-c) Desk light field interpolation using (a) proposed layer-based representation, (b) stereo matching algorithm  and (c) EPI tubes extraction method . (d-f) Dwarves EPI interpolated images in the same order. Note that the layer extraction algorithm has been implemented on the grayscale images. The obtained layers were then used to interpolate each of the RGB channels to show colour results.
