Adaptive Fragments-Based Tracking of Non-Rigid Objects Using Level Sets
We present an approach to visual tracking based on dividing a target into multiple regions, or fragments. The target is represented by a Gaussian mixture model in a joint feature...

The Remote Point Problem, Small Bias Spaces, and Expanding Generator Sets
Using ε-bias spaces over F2, we show that the Remote Point Problem (RPP), introduced by Alon et al [APY09], has an NC2 algorithm (achieving the same parameters as [APY09]). We stu...

Synthesis of irregular combinational functions with large don't care sets
A special logic synthesis problem is considered for Boolean functions which have large don’t care sets and are irregular. Here, a function is considered as irregular if the inpu...
