Continuous Ratio Optimization via Convex Relaxation with Applications to Multiview 3D Reconstruction
16 years 5 months ago
We introduce a convex relaxation framework to optimally
minimize continuous surface ratios. The key idea is to minimize
the continuous surface ratio by solving a sequence
of con...
