Pointlevel

Pointlevel is a term used in several disciplines to denote a discrete tier or annotation assigned to individual points in a dataset, model, or visualization. Its exact meaning is domain dependent, but it generally conveys depth, priority, or granularity of a point.

In computational geometry and computer graphics, pointlevel often refers to the depth or level of a point within a hierarchical spatial structure such as a quadtree or octree. The level correlates with cell size and processing order, influencing queries, rendering, and aggregation.

In topological data analysis, level commonly denotes a filtration parameter. A point's level is the parameter value at which it enters a sublevel or superlevel set as a function over the space is varied.

In computer vision, point-level annotations are a form of weak supervision for segmentation. A single point per object or class seeds labels, guiding region proposals or pixel-wise predictions while reducing labeling effort.

Outside these domains, pointlevel may describe the granularity of plotted data points or the indicated priority or confidence attached to a point in a processing pipeline. The term is not standardized and its meaning is context-dependent.
