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.

Safe hulls

IET 4th European Conference on Visual Media Production (CVMP 2007), 2007
The visual hull is widely used as a proxy for novel view synthesis in computer vision. This paper introduces the safe hull, the first visual hull reconstruction technique to produce a surface containing only foreground parts. A theoretical basis underlies this novel approach which, unlike any previous work, can also identify phantom volumes attached to

Ultimate strength assessment of ship hull structures subjected to cyclic bending moments

Ocean Engineering, 2020
The concept of “cyclic ultimate strength” of ship hull structures is proposed. In navigating in waves a ship is subjected to alternate bending moments in hogging and sagging conditions.

Extrusion followed by ultrasound as a chemical-free pretreatment method to enhance enzymatic hydrolysis of rice hull for fermentable sugars production

, 2020
The rice hull is an abundant and renewable biomass resource, which contains rich carbohydrates and can be used as an alternative energy source. In order to exploit and utilize the biomass energy in rice hull, extrusion and ultrasound technologies were ...

Optimization design of neutrally buoyant hull for underwater gliders

, 2020
The net buoyancy, driving force of underwater gliders, decreases gradually when the gliders dive or climb in the seawater, which increases the energy consumption and reduces the gliding range.

Minimal Hulls, Null Hulls, and Currents

2021
In this chapter we initiate the study of minimal hulls and null hulls of compact sets in Euclidean spaces. These hulls are defined by the maximum principle for minimal and null plurisubharmonic functions, in analogy to the classical polynomial and plurisubharmonic hulls of complex analysis.

Fuzzy counterparts of hull operators and interval operators in the framework of L-convex spaces

Fuzzy Sets Syst., 2019
For fuzzy counterparts of hull operators and interval operators, two types of fuzzy hull operators and one type of fuzzy interval operators are proposed.

Mutual Infective Hulls

Canadian Mathematical Bulletin, 1996
AbstractThe mutual injective hull of an arbitrary family of modules is constructed. Applications to the calculations of quasi-injective and π-injective hulls of direct sums are given.
