Semantic segmentation is a fundamental task in computer vision, playing a crucial role in various applications such as autonomous driving, medical image analysis, and object recognition. Deep learning models have shown remarkable performance in semantic segmentation, but their success largely depends on the availability of high-quality labeled datasets for training. The scarcity of diverse and comprehensive labeled datasets, especially in specific domains or for rare objects, hinders the development and evaluation of robust semantic segmentation models.

One promising solution to address the data scarcity problem is the generation of synthetic datasets. However, creating a synthetic dataset that accurately mimics real-world data remains a challenging task. Current synthetic datasets often suffer from unrealistic artifacts, which can lead to poor model generalization when trained on them.


The primary objectives of this research are as follows:

  1. Diffusion Model Adaptation: Investigate the adaptation and extension of diffusion models for generating high-quality synthetic datasets for semantic segmentation. This includes developing methods to ensure that generated images exhibit realistic object shapes, textures, and environmental contexts.
  2. Quality Assessment: Develop quantitative and qualitative metrics for assessing the quality of the synthetic dataset. Ensure that the dataset meets the necessary criteria for training and evaluating semantic segmentation models.
  3. Performance Improvement: Evaluate the extent to which semantic segmentation models trained on the synthetic dataset outperform models trained on existing synthetic datasets or when real data is scarce.

Relevant material

Required background

Applicants are expected to possess a comprehensive understanding of deep learning and computer vision, which will be essential for engaging with the research effectively.

Proficiency in Python coding is a prerequisite for implementing and experimenting with the proposed techniques.

While prior experience with diffusion models is highly valued, it is not mandatory, as this thesis will provide the necessary context and guidance for their application in generating realistic synthetic datasets for semantic segmentation.

Required application material

  • CV
  • Cover letter
  • Transcripts (with grades)

All application material must be in English.

Work starts in beginning of 2024
