Synthetic Dataset Generation Tool

Introducing Synthetic Dataset Generation to the Healthcare Industry using Unity Computer Vision and Perception Packages.

Introducing the latest innovation for healthcare: our powerful application designed to revolutionise the healthcare industry. Using Unity Computer Vision, we’ve developed an app that empowers our client to generate a vast array of images of their at-home finger-prick blood test kits.

We worked closely with our client and understand the importance of timely and precise responses in patient care, with a focus on efficiency and accuracy. That’s why our app harnesses the latest advancements in artificial intelligence and image recognition software, enabling healthcare providers to train their systems quickly and effectively.

How Does it Work?

Unity’s Perception package is designed to enhance supervised Machine Learning (ML) pipelines by providing new ways to generate a large quantity of labelled synthetic datasets using Unity Simulation.

We’ve incorporated these features into our application, and provided some user friendly controls for customising how these synthetic datasets are created, giving users control over lighting, scene clutter, quantity, and test kit specific settings.

All of this combined creates a powerful tool allowing users to generate a variety of custom datasets which can be used to train their AI image recognition tools with accurate life-like data without needing to manually construct and label thousands of images. Our client can now generate thousands of labelled synthetic datasets in minutes rather than weeks, leading to huge savings in both time and cost to train their AI model.

Tools like this are incredibly useful and powerful for training AI as they reduce the necessity to gather and label thousands of real-world images. Real-world images are of course desired in AI training (if not essential for a successful model), but Unity have shown that a model trained on both real-world and synthetic datasets increases accuracy:

“Mean Average Precision averaged across IoU thresholds of  [0.5:0.95] (mAP), Mean Average Precision with a single IoU threshold of 0.5 (mAPIoU=0.5), and the Mean Average Recall with a maximum of 100 detections (mAR) measured on a held-out set of 254 real-world images.”

1.1 Real World (760)0.480.730.59
1.2 Synthetic (400,000)0.400.620.52
1.3 Synthetic (400,000) + Real World (76)0.600.830.67
1.4 Synthetic (400,000) + Real World (380)0.680.890.74

Outcome

With just a few clicks, our client can now generate a large volume of datasets, each meticulously tagged and categorised to facilitate the training of their AI model. This streamlined process ensures that our partners have access to the most up-to-date and accurate data, ultimately leading to faster and more accurate responses for patients.

The software speeds up the process of both generative AI learning modelling and also validation and verification of existing algorithms and image analysis.
