MIT-Adobe FiveK Dataset

The MIT-Adobe FiveK Dataset [1] is a publicly available dataset providing the following items.

1. 5,000 RAW images in DNG format
2. retouched images of each RAW image by five experts in TIFF format (25,000 images, 16 bits per channel, ProPhoto RGB color space, and lossless compression)
3. semantic information about each image The dataset was created by MIT and Adobe Systems, Inc., and is intended to provide a diverse and challenging set of images for testing image processing algorithms. The images were selected to represent a wide range of scenes, including landscapes, portraits, still lifes, and architecture. The images also vary in terms of lighting conditions, color balance, and exposure. In practice, this dataset is often used after RAW images have undergone various processing steps. For example, RAW images are developed by adding noise, overexposure, and underexposure to emulate camera errors. However, the officially provided dataset has a complex structure and is difficult to handle. This repository provides tools to easily download and use the datasets.

Code

GitHub repository provides tools to download and use MIT-Adobe FiveK Dataset in a machine learning friendly manner. You can download the dataset with a single line of Python code. Also, you can use Pytorch's DetaLoader to iteratively retrieve data for your own use. The processing can be easily accomplished with multiprocessing with Pytorch's DataLoader!

Requirements

• Python 3.7 or greater
• Pytorch 2.X
• tqdm
• urllib3

Usage

You can use as follows.

NOTE: For DataLoader, MUST set `batch_size` to `None` to disable automatic batching.

from torch.utils.data.dataloader import DataLoader
from dataset.fivek import MITAboveFiveK

metadata_loader = DataLoader(
    MITAboveFiveK(root="path-to-dataset-root", split="train", download=True, experts=["a"]),
    batch_size=None, num_workers=2)

for item in metadata_loader:
    # Processing as you want.
    # Add noise, overexpose, underexpose, etc.
    print(item["files"]["dng"])

Example

Please see sample code .

API

CLASS MITAboveFiveK(torch.utils.data.dataset.Dataset)

---

MITAboveFiveK(root: str, split: str, download: bool = False, experts: List[str] = None) -> None

• root (str):
  The root directory where the MITAboveFiveK directory exists or to be created.
• split (str):
  One of {'train', 'val', 'test', 'debug'}. 'debug' uses only 9 data contained in 'train'.
• download (bool):
  If True, downloads the dataset from the official urls. Files that already exist locally will skip the download. Defaults to False.
• experts (List[str]):
  List of {'a', 'b', 'c', 'd', 'e'}. 'a' means 'Expert A' in the website. If None or empty list, no expert data is used. Defaults to None.
