🌌 Open-Pixel-1T (Visual Atlas)

A Large-Scale, High-Entropy Synthetic Image Dataset for Foundational Pre-Training

---

📑 Dataset Summary

Open-Pixel-1T is a monumental open-source initiative designed to create a "Visual Atlas" of stochastic imagery. Unlike traditional datasets scraped from social media which contain inherent human bias, Open-Pixel-1T is constructed using high-entropy random seeds to generate unique, diverse visual signals.

This dataset serves as a foundational layer for computer vision research, specifically targeting self-supervised learning (SSL), variational autoencoders (VAEs), and large-scale generative pre-training where data volume and variance are critical.

🚀 Roadmap & Scale

The project follows an aggressive expansion roadmap:

• Phase 1 (Current): 1 Terabyte (1TB) of high-resolution data.
• Phase 2: Expansion to 10 Terabytes (10TB).
• Phase 3: Long-term goal of 100 Terabytes (100TB) of open visual data.

🎯 Key Specifications

• Resolution: Standardized 1024x1024 px.
• Format: Optimized Apache Parquet (Snappy Compression).
• Source: Synthetic randomness via UUIDv4 seeding (Picsum Source).
• Entropy: Maximized randomness to prevent overfitting on specific visual domains.

💾 Dataset Structure

The dataset is sharded into ~1GB Parquet files to facilitate distributed training and streaming. Each row represents a unique image sample generated from a unique seed.

Data Fields

Field	Type	Description
image	image	The raw image binary (PIL compatible).
url	string	The source URL containing the unique seed used for generation.
seed	string	The UUIDv4 seed key responsible for the image's visual output.

Sample Data

{
  "image": "<PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1024x1024>",
  "url": "[https://picsum.photos/seed/a1b2-c3d4-e5f6/1024/1024](https://picsum.photos/seed/a1b2-c3d4-e5f6/1024/1024)",
  "seed": "a1b2-c3d4-e5f6"
}

🛠️ Usage

1. Streaming (Recommended)

Due to the massive size (1TB+), it is recommended to stream the dataset rather than download it entirely.

from datasets import load_dataset

# Stream the dataset (No disk space required)
dataset = load_dataset("LAYEK-143/Open-Pixel-1T", split="train", streaming=True)

# Iterate through images
for i, sample in enumerate(dataset):
    print(f"Processing image {i}: {sample['seed']}")
    image = sample['image']
    image.show()
    
    if i == 5: break

2. PyTorch DataLoader Integration

The dataset is optimized for high-throughput training pipelines.

import torch
from torch.utils.data import DataLoader
from datasets import load_dataset
from torchvision import transforms

# Define transforms
transform_pipeline = transforms.Compose([
    transforms.Resize((256, 256)),
    transforms.ToTensor(),
])

def process_batch(examples):
    examples["pixel_values"] = [transform_pipeline(img.convert("RGB")) for img in examples["image"]]
    return examples

# Load in streaming mode
dataset = load_dataset("LAYEK-143/Open-Pixel-1T", split="train", streaming=True)
dataset = dataset.map(process_batch, batched=True, remove_columns=["image", "url", "seed"])

# Create Loader
dataloader = DataLoader(dataset, batch_size=64)
