Parametric estimation of affine deformations of binary images
We consider the problem of planar object registration on binary images where the aligning transformation is restricted to the group of affine transformations. Previous approaches...

The Complexity of Making Unique Choices: Approximating 1-in- k SAT
We study the approximability of 1-in-kSAT, the variant of Max kSAT where a clause is deemed satisfied when precisely one of its literals is satisfied. We also investigate differ...
