DDA-COCO Benchmark

Official Dataset for Dual Data Alignment Makes AI-Generated Image Detector Easier Generalizable

Conference: 39th Conference on Neural Information Processing Systems (NeurIPS 2025) https://arxiv.org/abs/2505.14359


Dataset Description

DDA-COCO is a benchmark specifically designed to evaluate whether AIGI detectors rely on "non-causal features" (such as compression artifacts or content semantics).

Many existing detectors experience significant performance drops when tested on strictly aligned data, as they tend to learn dataset biases rather than intrinsic generation artifacts. DDA-COCO includes real images from the MSCOCO validation set and their corresponding synthetic images, processed with various VAE reconstructions and frequency alignments, to test detector robustness.

Content

The dataset contains 5 subsets corresponding to different VAE model reconstructions:

  • Source: MSCOCO Validation Set (Real).
  • Variations: Synthetic images reconstructed by different VAE versions (e.g., SD1.5, SD2.1, SDXL) with frequency alignment.
  • Key Feature: High consistency between real and synthetic images in semantics, size, and frequency distribution, forcing detectors to focus on subtle generative traces.
