Beyond Bounding-Box: Convex-hull Feature Adaptation for Oriented and Densely Packed Object Detection

Computer Vision and Pattern Recognition, 2021
Detecting oriented and densely packed objects remains challenging for spatial feature aliasing caused by the intersection of reception fields between objects.

Technical Note - Convex Programming with Set-Inclusive Constraints and Applications to Inexact Linear Programming

Operational Research, 1973
This note formulates a convex mathematical programming problem in which the usual definition of the feasible region is replaced by a significantly different strategy.

Convexity and convex sets [PDF]

, 2010
The history of convexity History of convexity is rather astonishing, even paradoxical, and we explain why. On the one hand, the notion of convexity Convexity is extremely natural, so much so that we find it, for example, in works on artArt and anatomyAnatomy without it being defined.

On the Chvátal–Gomory closure of a compact convex set

Mathematical programming, 2010
In this paper, we show that the Chvátal–Gomory closure of any compact convex set is a rational polytope. This resolves an open question of Schrijver (Ann Discret Math 9:291–296, 1980) for irrational polytopes, and generalizes the same result for the case

Convex Sets and Convex Functions [PDF]

, 2011
We have encountered convex sets and convex functions on several occasions. Here we would like to discuss these notions in a more systematic way. Among nonlinear functions, the convex ones are the closest ones to the linear, in fact, functions that are convex and concave at the same time are just the linear affine functions.

Robust Convex Optimization

Mathematics of Operations Research, 1998
We study convex optimization problems for which the data is not specified exactly and it is only known to belong to a given uncertainty set U, yet the constraints must hold for all possible values of the data from U.
