Student assistant in the field of analysis of optical material behavior using machine learning
Vor 2 Tagen
The Competence Center of Autonomous Digitization Technologies at Fraunhofer IGD develops and automates 3D scanning technologies to allow for automatic 3D reconstruction of cultural heritage and industrial objects. Different acquisition devices are used depending on the object properties and quality requirements. We research modern machine-learning methods for the analysis of an object's optical surface behavior. For this purpose, a solution was developed to infer a surface's material composition based on its optical properties. Be part of change The core task is to take over the development of a model for the classification and segmentation of various materials based on their optical properties. These material properties are available as Bi-directional Texture Functions (BTF) and are used as training data for a neural network. Python with PyTorch is used for software development.This project requires expanding the system to larger datasets as well as applying the technology to hyperspectral data, i.e., surface scans captured with more channels than RGB. For this, it must be researched which features are relevant for the given task and based on that, the model must be adapted.Additionally, the model should be integrated into our production environment to make the execution and results of analyses easily accessible. What you contribute Very good C++ programming skills Very good Python skills Strong knowledge in mathematics and linear algebra Proficient English skills Precise, responsible, independent working style Experience with PyTorch and machine-learning approaches Experience with the frameworks Qt and OpenCV is advantageous The weekly working time is 10-20 hours. The position is initially limited to three months, an extension is intended. We value and promote the diversity of our employees' skills and therefore welcome all applications – regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, sexual orientation and identity. Severely disabled persons are given preference in the event of equal suitability.
