In the present work, we consider Zuckerberg's method for geometric convex-hull proofs introduced in [Geometric convex hull defining formulations, Operations Research Letters 44(5), 625-629 (2016)]. It has only been scarcely adopted literature so far, despite great flexibility designing algorithmic completeness of polyhedral descriptions that it offers. We suspect this is partly due to rather he...

sar (synthetic aperture radar) image enhancement and segmentation is purpose of this thesis. sar image segmentation is a primary step before steps such as classification and target recognition. the main obstacle in sar image segmentation is inherent speckle noise. speckle noise is a multiplicative and highly destructive noise which results to intensity inhomogeneity. hence common segmentation m...

We give necessary and sufficient conditions, both algebraic geometric, for a quadrilateral to be the level set of sum distances m ≥ 2 different lines.
