Regeneration of ornamental plants: current status and prospects

Ornamental Plant Research
For horticulture to meet the needs of global markets, the reproduction and breeding of ornamental plants is allimportant. Nevertheless, certain ornamental plants exhibit a lower capacity for explant regeneration when compared to model plants.

Historical Printed Ornaments: Dataset and Tasks [PDF]

arXiv
This paper aims to develop the study of historical printed ornaments with modern unsupervised computer vision. We highlight three complex tasks that are of critical interest to book historians: clustering, element discovery, and unsupervised change localization.

Challenges in Plane Symmetry: From Theory to Perception [PDF]

arXiv
The planar ornaments are created by repeating a base unit using a combination of four primitive geometric operations: translation, rotation, reflection, and glide reflection. According to group theory, different combinations of these four geometric operations lead to different symmetry groups.

The Pop-Stack Operator on Ornamentation Lattices [PDF]

arXiv
Each rooted plane tree $\mathsf{T}$ has an associated ornamentation lattice $\mathcal{O}(\mathsf{T})$. The ornamentation lattice of an $n$-element chain is the $n$-th Tamari lattice. We study the pop-stack operator $\mathsf{Pop}\colon\mathcal{O}(\mathsf{T})\to\mathcal{O}(\mathsf{T})$, which sends each element $\delta$ to the meet of the elements ...

ORNAMENTAL PLANTS IN DIFFERENT APPROACHES

, 2020
Today, some ornamental plants are used in soil reclamation and erosionprevention activities, targeting different landscape restoration purposes.Naturally occurring erosion can be exacerbated by humaninterventions, especially in vegetation. For this reason, afforestationand improvement of the existing vegetation are of great importance inplanning areas ...
