ROSCOSMOS/Church_Buildings

Churches

High resolution image subset from the Aesthetic-Train-V2 dataset, a collection of Church buildings including facades, interior shots and landscapes.

Dataset Details

• Curator: Roscosmos
• Version: 1.0.0
• Total Images: 780
• Average Image Size (on disk): ~5.8 MB compressed
• Primary Content: Church buildings
• Standardization: All images are standardized to RGB mode and saved at 95% quality for consistency.

Dataset Creation & Provenance

1. Original Master Dataset

This dataset is a subset derived from: zhang0jhon/Aesthetic-Train-V2

• Link: https://huggingface.co/datasets/zhang0jhon/Aesthetic-Train-V2
• Providence: Large-scale, high-resolution image dataset, refer to its original dataset card for full details.
• Original License: MIT

2. Iterative Curation Methodology

CLIP retrieval / manual curation.

Dataset Structure & Content

This dataset offers the following configurations/subsets:

• Default (Full train data) configuration: Contains the full, high-resolution image data and associated metadata. Each example (row) in the dataset contains the following fields:

• image: The actual image data. In the default (full) configuration.

• unique_id: A unique identifier assigned to each image.

• width: The width of the image in pixels (from the full-resolution image).

• height: The height of the image in pixels (from the full-resolution image).

Usage

To download and load this dataset from the Hugging Face Hub:

from datasets import load_dataset, Dataset, DatasetDict

# Login using e.g. `huggingface-cli login` to access this dataset

# To load the full, high-resolution dataset (recommended for training):
# This will load the 'default' configuration's 'train' split.
ds_main = load_dataset("ROSCOSMOS/Church_Buildings", "default")

print("Main Dataset (default config) loaded successfully!")
print(ds_main)
print(f"Type of loaded object: {type(ds_main)}")

if isinstance(ds_main, Dataset):
    print(f"Number of samples: {len(ds_main)}")
    print(f"Features: {ds_main.features}")
elif isinstance(ds_main, DatasetDict):
    print(f"Available splits: {list(ds_main.keys())}")
    for split_name, dataset_obj in ds_main.items():
        print(f"  Split '{split_name}': {len(dataset_obj)} samples")
        print(f"  Features of '{split_name}': {dataset_obj.features}")
