Master Thesis in Deep Learning for Model-Based 6DoF Object Pose Estimation

 

The Augmented Vision Department of DFKI led by Prof. Dr. Didier Stricker is offering a Master Thesis topic for curious and passionate students, who want to develop themselves in advanced Deep Learning and 3D Computer Vision. (More guidance and specifics about the thesis will be discussed in the initial interview)

Main Tasks:

  • In-depth literature review of recent 6DoF Object Pose Estimation approaches and review of various datasets [2] used in evaluating these methods
  • Developing a novel approach to Object Pose Estimation [1] using recent Deep Learning models such as Transformers [3]
  • Extensive experimentation and ablation studies on various Object Pose Datasets and comparison to state-of-the-art approaches
  • Potentially submitting a concise paper to a Computer Vision conference

Requirements

  • Good knowledge of concepts in 3D Computer Vision and Deep Learning
  • High-level experience in Python and PyTorch/TensorFlow
  • Previous experience in image rendering / dataset creation software like Blender is beneficial

Master Thesis in Accurate 3D Geometry Generation with GANs (m/w/d)

GANs have made significant strides since their inception in 2014, demonstrating remarkable capabilities in generating realistic audio and video mixes, as well as complex geometries. However, a persistent challenge lies in ensuring the accuracy of the generated results. While the visual appeal of these results may be convincing, they often fail to faithfully represent the genuine geometric properties they aim to emulate. A pertinent example is the simulation of paper folding and crumpling, where maintaining the inherent geometric characteristics of the sheet (e.g., preventing stretching) is crucial. Although deterministic simulations of paper deformation have been developed, comprehending and replicating them often necessitate an extensive understanding of material physics, mathematics, and computer graphics. One potential approach to address this challenge involves harnessing the power of GANs or other network architectures, such as variational autoencoders, to analyze 3D geometries and generate highly accurate representations. However, several hurdles must be overcome, including operating effectively within the 3D space and establishing a robust methodology to evaluate the fidelity of the output geometries. An intriguing application of such methods for generating 3D geometries lies in their ability to rapidly generate synthetic data with exceptional accuracy. This synthesized data can then be employed for training purposes in various domains, offering a valuable resource for enhancing learning algorithms and expanding their applicability.

Tasks

  • State-of-the-art review on GANs and paper simulation
  • Generating paper geometries using simulation
  • Use GANs to generate geometries and designing accuracy and comparison methodology
  • Evaluating generated results from GANs and possible refinement strategies

Requirements

  • 3D computer vision, Computer graphics, Geometric modelling
  • Deep Learning (TensorFlow, PyTorch, Keras)
  • C++ (OpenGL, OpenCV), Python, C#
