In this paper we present a differential approach to photopolarimetric shape estimation. We propose several alternative differential constraints based on polarisation and photometric shading information and show how to express them in a unified partial differential system. Our method uses the image ratios technique to combine shading and polarisation information in order to directly reconstruct surface height, without first computing surface normal vectors. Moreover, we are able to remove thedoi:10.1109/iccv.2017.250 dblp:conf/iccv/TozzaSZRH17 fatcat:sn4exwjsqncfnitss5xjhzufsu
