This repository hosts the processed dataset files for WPRF_open (omvis).

Summary

Content: RGB images + instance segmentation annotations in COCO format.
Packaging: zip artifacts (for robust download & integrity check).

Files

file	sha256	size
`data.zip`	`5d39968d4657b26b0f16fa4f77a63147f6d68eec252ce9ac75bd585ab2f55b85`	0.16 GB

Statistics (COCO)

split	images	annotations
`train`	149	149
`val`	21	21
`test`	42	42
total	212	212

Layout

After downloading and extracting the zip file(s), the dataset root is:

<dataset_root>/
  images/{train,val,test}/...           # `val` is optional
  annotations/instances_{train,val,test}.json  # `val` is optional

Notes

This dataset is provided for research use.
Please check the original dataset license/terms before redistribution.
