SEEDS: Superpixels Extracted via Energy-Driven Sampling
TLDR
A robust and fast to evaluate energy function is defined, based on enforcing color similarity between the boundaries and the superpixel color histogram, which is able to achieve a performance comparable to the state-of-the-art, but in real-time on a single Intel i7 CPU at 2.8GHz. Expand

Generators and representability of functors in commutative and noncommutative geometry
We give a sufficient condition for an Ext-finite triangulated category to be saturated. Saturatedness means that every contravariant cohomological functor of finite type to vector spaces isExpand
Some Algebras Associated to Automorphisms of Elliptic Curves
The main object of this paper is to relate a certain type of graded algebra, namely the regular algebras of dimension 3, to automorphisms of elliptic curves. Some of the results were announced inExpand
Double Poisson algebras
In this paper we develop Poisson geometry for non-commutative algebras. This generalizes the bi-symplectic geometry which was recently, and independently, introduced by Crawley-Boevey, Etingof andExpand
Non-commutative Crepant Resolutions
We introduce the notion of a “non-commutative crepant” resolution of a singularity and show that it exists in certain cases. We also give some evidence for an extension of a conjecture by Bondal andExpand

A RELATION BETWEEN HOCHSCHILD HOMOLOGY AND COHOMOLOGY FOR GORENSTEIN RINGS
Let “HH” stand for Hochschild (co)homology. In this note we show that for many rings A there exists d ∈ N such that for an arbitrary Abimodule N we have HHi(N) = HHd−i(N). Such a result may be viewedExpand
