• Abstract summary: We introduce a strategy to generate a synthetic dataset of microbiological images of Petri dishes that can be used to train deep learning models. We show that the method is able to synthesize a dataset of realistic looking images that can be used to train a neural network model capable of localising, segmenting, and classifying five different microbial species.

• Abstract: We introduce an effective strategy to generate a synthetic dataset of microbiological images of Petri dishes that can be used to train deep learning models. The developed generator employs traditional computer vision algorithms together with a neural style transfer method for data augmentation. We show that the method is able to synthesize a dataset of realistic looking images that can be used to train a neural network model capable of localising, segmenting, and classifying five different microbial species. Our method requires significantly fewer resources to obtain a useful dataset than collecting and labeling a whole large set of real images with annotations. We show that starting with only 100 real images, we can generate data to train a detector that achieves comparable results to the same detector but trained on a real, several dozen times bigger dataset. We prove the usefulness of the method in microbe detection and segmentation, but we expect that it is general and flexible and can also be applicable in other domains of science and industry to detect various objects.

  Quantifying axon and myelin properties in histology images can provide useful information about microstructural changes caused by neurodegenerative diseases. Advances in deep learning have made this task quick and reliable with minimal overhead, but a deep learning model trained by one research group will hardly ever be usable by other groups. There is a pressing need to make AI accessible to researchers to facilitate and accelerate their workflow, but publicly available models are scarce and poorly maintained. Our approach is to aggregate data from multiple imaging modalities to create an open-source, durable tool for axon and myelin segmentation.

  Eye image segmentation is a critical step in eye tracking that has great influence over the final gaze estimate.

Our methods result in robust, improved performance when tackling the discrepancy between simulation and real-world data samples.

We show that our model is strongly robust to missing information to an extent that it can achieve the same performance with as low as 20% of the data.
