Dataset Card for Dreambooth Brightfield Microscopy

This dataset was created as part of my masters research and thesis, where I am trying to generate realistic looking brightfield microscopy images for dataset augmentation. With the downstream goal of enhancing cell detection objects, increasing the dataset size of an object detection model is a necessary step.

Dataset Description

As part of my research, I previously generated brightfield microscopy images using unconditional diffusion models, curating a large dataset of SCC brightfield images. The results of these models were pretty impressive, but still needed many images. Hence, this dataset was created to test the capabilities of dreambooth on brightfield microscopy image generation. I'm testing several configurations:

• Diffusion Model Architectures (SD-1.5(, SD-2.1, SDXL 1.0)) -- The last two had to be discontinued due to time, and compute constraints
• Training Data Size (10, 20, 30, 50)
• 4 Concepts are trained in parallel (cell, cell rug, well edge, debris)
• With and without subject class images for class-specific prior preservation loss impact assessment

The dataset consists of several classes:

• Real microscopy images, one class for each concept
• Generated images from SD-1.5, one class for each concept
• Generated images from SD-2.1, one class for each concept
• Generated images from SDXL 1.0, one class for each concept

These classes are used in the concepts for the dreambooth model training, resulting in 8 models trained to assess the usability of dreambooth in this domain. Unfortunately, due to time constraints, I'm not able to test many hyperparameter configurations for each model, nor play around a lot with prompt engineering. This research serves as a base thath others (or me) can work upon.
