rplatypus: Computer Vision for Medical Imaging

Semantic segmentation and object detection for medical images, from a folder of pictures to a trained model and a figure, in a handful of lines or one configuration file. Architectures, losses and training run on 'PyTorch' through 'pyplatypus', a 'Python' package which is installed and isolated automatically; nothing has to be set up by hand. R keeps the parts that make an analysis fast - reading and combining masks, drawing boxes, plotting, comparing models.

NeedsCompilation: no
SystemRequirements: Python (>= 3.10). Not a prerequisite the user installs: the package declares what it needs through 'reticulate' and 'uv' provisions an isolated environment on first use, leaving any system Python untouched.
