Line Geometry for 3D Shape Understanding and Reconstruction
We understand and reconstruct special surfaces from 3D data with line geometry methods. Based on estimated surface normals we use approximation techniques in line space to recogniz...

Using Optical Emission Analysis for Estimating Contribution to Power Analysis
—This paper shows that optical emissions from an operating chip have a good correlation with power traces and can therefore be used to estimate the contribution of different area...
