Glossary¶
A collection of common terms used in torchgeo that may be unfamiliar to either:
Deep learning researchers who don’t know remote sensing
Remote sensing researchers who don’t know deep learning
- area of interest (AOI)¶
Synonym for region of interest (ROI). A particular spatial area to focus on.
- chip¶
Synonym for patch. A smaller image sampled from a larger tile.
- classification¶
A computer vision task that involves predicting the image class for an entire image or a specific bounding box.
- coordinate reference system (CRS)¶
Synonym for spatial reference system (SRS). A system that defines how to locate geographic entities on a projected surface.
- instance segmentation¶
A computer vision task that involves predicting labels for each pixel in an image such that each object has a unique label.
- object detection¶
A computer vision task that involves predicting bounding boxes around each object in an image.
- patch¶
Synonym for chip. A smaller image sampled from a larger tile.
- projection¶
A geometric transformation for portraying the surface of a 3D Earth onto a 2D planar image.
- region of interest (ROI)¶
Synonym for area of interest (AOI). A particular spatial region to focus on.
- regression¶
A computer vision task that involves predicting a real valued number based on an image.
- semantic segmentation¶
A computer vision task that involves predicting labels for each pixel in an image such that each class has a unique label.
- spatial reference system (SRS)¶
Synonym for coordinate reference system (CRS). A system that defines how to locate geographic entities on a projected surface.
- stitching¶
Combining a collection of patches into a single image. This is the reverse operation of tiling.
- swath¶
A set of tiles along a satellite trajectory.
- tile¶
A single image file taken by a remote sensor like a satellite.
- tiling¶
Splitting a tile into patches. This is the reverse operation of stitching.
