-== Depth-Adaptive Superpixels (BA/HiWi)==+== Game Engine Developer and 3D-Modelling  (Student Job / HiWi) == 
 +A recent development in the field of AI is the usage of photorealistic simulations, for example to create Digital Twins of environments like households or  [[https://iottechnews.com/news/2021/apr/13/bentley-systems-nvidia-omniverse-create-real-time-digital-twins/|factories]]. 
 +In our research group, we focus on the development of modern robots that can make use of the potential of game engines. This requires a high degree of specialized game engine plugins that can simulate certain aspects of our research. Another important task is the creation of 3d models.
  
-We are currently investigating a new set of sensors (RGB-D-T), which is a combination of a kinect with a thermal image camera. Within this project we want to enhance the Depth-Adaptive Superpixels (DASP) to make use of the thermal sensor data. Depth-Adaptive Superpixels oversegment an image taking into account the depth value of each pixel. {{ :research:dt_dasp.png?200|}} +Therefore, we are currently offering multiple Hiwi positions / student jobs for the following tasks: 
- +  * Modelling of objects for the use in Unreal Engine 4. 
-Since the current implementation of DASP is not very performant for high resolution images, there are several possibilities options for doing a project in this field like reimplementing DASP using the CUDA, investigating how thermal data can be integrated, ...+  * Creation of specific simulation aspects in Unreal Engine 4. For example the development of interactable objects.
  
 Requirements: Requirements:
-  * Basic knowledge of image processing +  * Knowledge of 3D-Modelling tools. Blender would be highly preferred.
