View synthesis from needle-maps

摘要

Investigates the use of shape from-shading for view synthesis. Theaim of our study is to determine whether needle-maps delivered by a newshape-from-shading (SFS) algorithm can be used as a compact objectrepresentation. Specifically, we aim to show that the needle maps can beused to generate novel object views. To this end we conduct two sets ofexperiments. Firstly, we use the recovered needle maps to re-illuminateobjects under varying lighting directions. Here we show that a singleinput image can be used to construct faithful re-illuminations underradical illumination changes. Secondly, we investigate how the needlemap can be used to generate new object poses. Here we show thatneedle-maps can be used for both view interpolation and viewextrapolation
