Jiuqiang Han · Systems engineering and electronics · 2008
A direct algorithm of Shape-From-Shading based on hybrid reflection is proposed.Hybrid reflection models which contain diffuse reflectance and specular reflectance are used as objective equations.When the differential operators are approximated by finite difference,the algebra equations about unknown surface are gained.Then the equations are solved using iterative approach.At last,experiments on synthetic images and real images are performed to illuminate the efficiency of the present method.
