- Course objectives
- The course brings the basic overview of digital geometry. We will discuss problems that arise from object digitalization and their representation by the set of points on a grid (e.g, digital image). Especially, we will define the basic terms (adjacency, connectedness, boundary, etc.) and show how to measure geometric as well as topologic properties of digital sets (distance, length, volume, etc.).
- Digital image, pixel, voxel, image resolution
- Types of grids, grid point and grid cell models, adjacency vs. incidence, switch adjacency
- Connectedness and components, component labeling
- Measurement in digital images: metrics, integer-valued metrics, regular metric, approximation to Euclidean metric, chamfer distance
- Distance transform
- Distance measurement between sets
- Digital sets: digital line, digital circle, etc.
- Estimation and computation of geometric and topological properties of digital sets: volume, surface, area, perimeter, length, curvature, Euler characteristic, etc.
- Boundary and border and their computation
