In this paper we address the problem of relighting faces in presence of cast shadows and specularities. We present a solution to this problem by capturing the spatially varying Apparent Bidirectional Reflectance Functions (ABRDF) fields of human faces using Spline Modulated Spherical Harmonics and representing them using a few salient spherical functions called Eigenbubbles. Through extensive experiments...
In this paper we show that the features generated by the recently presented Invariant Features of Local Textures (IFLT) technique can be used in a SIFT like framework to deliver real-time point wise image matching with performance comparable to existing state-of-the-art image matching systems. The proposed framework is also capable of saving considerable amount of computation time.
Illumination and view dependent texture provide ample information on the appearance of real materials at the cost of enormous data storage requirements. Hence, past research focused mainly on compression and modelling of these data, however, few papers have explicitly addressed the way in which humans perceive these compressed data. We analyzed human gaze information to determine appropriate texture...
