Endava Synthetics presents its workflow for producing synthetic training data with an end-to-end pipeline built on top of Houdini. By leveraging Houdini’s core functionality and incorporating machine learning concepts, they produce synthetic datasets used to train machine vision algorithms to detect fillings and cavities in dental x-ray imagery - involving different x-ray types like bite wing and periapical, generating dental anatomy and defects, using synthetic data to aid routine analysis, freeing up dentist time for more complex tasks.
