Procedural Generation of Synthetic Data Outperforms Manual Curation for Multi-View Stereo Training

Synthetic datasets generated through simple, rule-based procedural methods can achieve superior performance in training Multi-View Stereo (MVS) models compared to manually curated datasets.

arXiv preprint · 2026

Key Findings

01Procedurally generated data at a modest scale (8,000 images) outperformed manually curated data at the same scale.
02Scaling procedural generation to 352,000 images resulted in performance comparable to, and in some cases exceeding, models trained on over 692,000 manually curated images.

Application

Design takeaway

Prioritize the development of procedural generation systems for creating training data when manual curation is time-consuming or resource-intensive, especially for tasks like MVS.

How to apply

When developing AI models that require large visual datasets, explore procedural generation techniques to create synthetic training data that mimics real-world scenarios.

Project actions

01Consider using procedural generation tools to create custom datasets for your design projects.
02Document the rules and parameters used in your procedural generation process thoroughly.

Method & Evidence

AimTo investigate whether fully procedural synthetic data generation, driven by a minimal set of rules, can yield superior training data for Multi-View Stereo (MVS) compared to manually curated datasets.

MethodProcedural data generation and comparative performance analysis.

ProcedureA procedural generator (SimpleProc) was developed using Non-Uniform Rational Basis Splines (NURBS), displacement, and texture patterns to create synthetic images. Datasets of varying scales (8,000 and 352,000 images) were generated and used to train MVS models. The performance of these models was then benchmarked against models trained on manually curated datasets of similar and larger scales.

Sample8,000 to 352,000 synthetic images; 8,000 to 692,000 manually curated images.

ContextComputer Vision, specifically Multi-View Stereo (MVS) model training.

Variables

IVData generation method (procedural vs. manual curation).

DVPerformance of Multi-View Stereo models (e.g., accuracy, reconstruction quality).

CVDataset scale, MVS model architecture, training parameters, evaluation metrics.

Strengths & Limitations

Strengths

+Demonstrates significant performance gains with procedural generation.
+Provides open-source code and data for reproducibility.

Limitations

The realism of procedurally generated data might not perfectly match real-world scenarios, potentially leading to a domain gap in model performance.

Reliability & validity

The study's validity is supported by comparative benchmarking against established datasets and metrics. Reliability is enhanced by the availability of source code and data, allowing for replication.

Think critically

To what extent can the 'simplicity' of procedural rules be generalized across different computer vision tasks, and what are the potential limitations of relying solely on synthetic data?

Design Principles

"Leverage procedural generation to create high-quality, scalable synthetic datasets for training machine learning models."

This challenges traditional approaches to data acquisition for complex visual tasks. It suggests that designers and researchers can leverage procedural generation to create highly effective training data more efficiently, potentially reducing costs and time associated with manual data collection and annotation.

What This Means for Your Design

Making computer-generated images using simple rules can be better for teaching AI than using real photos that someone had to collect and sort.
