Semantic segmentation of Embryos in microscopy images

This repository includes training and inference code, as well as pre-trained weights for semantic segmentation of early life history stages of some species. Semantic segmentation is achieved through popular encoder-decoder architectures such as UNet and DeepLab V3. Currently there are only weights available for the segmentation of embryos of Lymnaea stagnalis, though this could be extended to other species with suitable training data. Results of these models are shown below as well as the links to the pre-trained models:

Performance of different models on Lymnaea stagnalis embryo segmentation

name resolution binary iou #params model
UNet 256x256 96.2 8M model
UNet++ 256x256 88.5 5M model
UNet3+ 256x256 95.3 11M model
SegNet 256x256 96.1 18M model
FCN 256x256 93.9 33M model
PSPNet 256x256 95.5 7M model
DeepLabV3+ 256x256 95.8 11M model
HRNetV2 256x256 95.9 9M model

If you want to reproduce the results above, simply download and extract the Lymnaea dataset included in the v0.1 release, and run the train_embryo.ipynb notebook with this data.

Lymnaea stagnalis image dataset

Images and annotations for training are included in this repository in the release with model weights - you can download the dataset using the following link. Note that the images used for this dataset were captured with the OpenVim phenotyping platform.
