        **Background**
        
        ![Project Workflow](https://github.com/Nelson-Gon/cytounet/blob/master/examples/project_workflow.png?raw=true)
        
        This project was largely done as a summer 2020 intern in Dr. Mikael [Bjorklund](https://person.zju.edu.cn/en/H118035)'s  
        lab, whose guidance, resources, and time I am grateful for. 
        
        The aim was to automate [a549](https://en.wikipedia.org/wiki/A549_cell) and [rpe](https://en.wikipedia.org/wiki/Retinal_pigment_epithelium) 
        cancer cell segmentation and size determination. 
        
        ![RPE Sample](https://github.com/Nelson-Gon/cytounet/blob/master/examples/rpe_sample.png?raw=true)
        
        Sample data(10 random images each of train, validate, test sets) is provided in [original_data](https://github.com/Nelson-Gon/cytounet/tree/master/examples/original_data/a549).
        
        A complete a549 cancer cell [segmentation notebook](https://github.com/Nelson-Gon/cytounet/blob/20435549e6b4c3d15979c2117445c4c19ab51bdf/examples/a549_sampler.ipynb) 
        is also provided. 
        
        Finally, pre-trained [weights](https://github.com/Nelson-Gon/cytounet/blob/56694553e5014e3f479807de244f5ddeabbcbf80/models/a549_scratch.hdf5) 
        are provided that can be used for transfer learning. 
        These were trained on considerably more data and for more epochs. For more pre-trained weights and/or data, 
        please [contact](https://nelson-gon.github.io/contact) the author. 
        
        **Note**
         
        * To generate masks(labels) provided here `a549` cancer cells were stained and imaged with fluorescence microscopy. These 
        fluorescent images were then thresholded with `threshold_images` with a threshold value of 83. The images were then saved 
        with `save_images`. The original fluorescent images are not provided here mainly due to the already huge size of the 
        project. 
        
        * This project is not limited to cancer cells. The model can be trained on almost any object, living and non-living.
        More examples are given below.

        **Installation**
        
        From `PyPI`:
        
        ```
        
        pip install cytounet
        
        ```
        
        
        From source or to use without installing locally:
        
        ```

        # proceed with usual source build procedure
        
        ```
        
        Or:
        
        ```
        
        pip install git+https://github.com/Nelson-Gon/cytounet.git
        
        ```
        
        **Import**

        **Experiments/Benchmarks**
        
        This section shows some experimental results based on publicly available data. 
        
        * Comparison of low vs high quality masks on the model's output
        
        This notebook shows the effects of "filled holes"(outlines whose area is filled with some colour e.g. white)
        on the model's quality. The results in general show that filled masks which are also better seen by the human eye
        result in better quality output. 
        
        The [notebook](https://github.com/Nelson-Gon/cytounet/blob/9781a45260bd8cdb82b37e07a26254ecf01af5c7/examples/example_usage.ipynb) can be accessed via this [link](https://nbviewer.jupyter.org/github/Nelson-Gon/cytounet/blob/9781a45260bd8cdb82b37e07a26254ecf01af5c7/examples/example_usage.ipynb).

        **Credits**
        
        * This repository started out as a clone of [zhixuhao](https://github.com/zhixuhao)'s  original 
        unet [implementation](https://github.com/zhixuhao/unet/).
        
        This repository has considerably diverged from the original implementation hence the need
        to distribute it separately. 
        
        This decision was taken in part due to the relative inactivity of the original implementation which would have made
        it harder to collaborate. 
        Please take a look at the list of [changes](https://github.com/Nelson-Gon/cytounet/blob/master/changelog.md) 
        from the original implementation. 
        
        * The Unet algorithm was introduced by Ronneberger et al. in their 
          [paper](https://link.springer.com/chapter/10.1007%2F978-3-319-24574-4_28).
