cuCIM

RAPIDS cuCIM (pronounced "koo-sim", see here) is an open-source, accelerated computer vision and image processing software library for multidimensional images used in biomedical, geospatial, material and life science, and remote sensing use cases.

cuCIM offers:

Enhanced Image Processing Capabilities for large and n-dimensional tag image file format (TIFF) files
Accelerated performance through Graphics Processing Unit (GPU)-based image processing and computer vision primitives
A Straightforward Pythonic Interface with Matching Application Programming Interface (API) for Openslide

cuCIM supports the following formats:

Aperio ScanScope Virtual Slide (SVS)
Philips TIFF
Generic Tiled, Multi-resolution RGB TIFF files with the following compression schemes:
- No Compression
- JPEG
- JPEG2000
- Lempel-Ziv-Welch (LZW)
- Deflate

NOTE: For the latest stable README.md ensure you are on the main branch.

Downloading sample images

To download images used in the notebooks, please execute the following commands from the repository root folder to copy sample input images into notebooks/input folder:

(You will need Docker installed in your system)

./run download_testdata

or

mkdir -p notebooks/input
tmp_id=$(docker create gigony/svs-testdata:little-big)
docker cp $tmp_id:/input notebooks
docker rm -v ${tmp_id}
