Real-time correction of panoramic images using hyperbolic Möbius transformations
Luis Peñaranda, Luiz Velho, Leonardo Sacht
Wide-angle images gained a huge popularity in the last years due to the development of computational photography and imaging technological advances. They present the information of…
Faster Geometric Algorithms via Dynamic Determinant Computation
Vissarion Fisikopoulos, Luis Peñaranda
The computation of determinants or their signs is the core procedure in many important geometric algorithms, such as convex hull, volume and point location. As the dimension of the…
An Oracle-based, Output-sensitive Algorithm for Projections of Resultant Polytopes
Ioannis Z. Emiris, Vissarion Fisikopoulos, Christos Konaxis +1
We design an algorithm to compute the Newton polytope of the resultant, known as resultant polytope, or its orthogonal projection along a given direction. The resultant is fundamen…
