CNN-CELL-COUNTING

• This is a well-structured Machine Learning microservice enables RESTful API.
• Finished as my Master Degree's Research project under Dr.Andrey Kan and Dr. Vinh Nguyen's supervision in 2016.
• Uses to count the number of cells in a medical image based on CNN & other algorithms.
• Relevant dissertation and demo slides can be viewed in document folder.
• Structure used for building in this case is flask.
• Any questions please contact Jizhizi Li [jizhizili@gmail.com]
• Relevant docker repository is here

How to Setup

Step 1: Create a new conda virtual env. - conda create -n $name python=3.6

Step 2: Go into virtual env. - source activate $name

Step 3: Install all the required packages - pip install -r requirements

Step 4: Install matplotlib seperately - conda install matplotlib

Step 5: Deactivate the env - source deactivate $name

How to Run App

Step 1: Run the virtual env Source activate $name

Step 2: Run python run.py to start

Routes

1. POST /print_coordinate:

   {
       "num":3
   }

   Give a specific number of image you want to process, get the well with coordinate printed in save folder.

2. POST /plot_data:

   {
       "plot_name":"train_plot"
   }

   Give a pkl name, plots data and label on image.

3. POST /generate_dataset:

   {
       "cell_size": 5,
       "crop_length": 50,
       "crop_width": 50,
       "crops_number_per_image": 60,
       "images_range": [
           1,
           3
       ],
       "save_name": "train"
   }

   Pass some parameters to generate a balanced labelled dataset used for training and testing.

4. POST /linear_model:

   {
       "test": {
           "choice": 1,
           "data_set": "test"
       },
       "train": {
           "choice": 1,
           "data_set": "train"
       }
   }

   Pass some parameters to train linear model on training set and test on testing set. Relevant logs and figs will be generated.

5. POST /logistic_model:

   {
       "test": {
           "choice": 1,
           "data_set": "test"
       },
       "train": {
           "choice": 2,
           "data_set": "train"
       }
   }

   Pass some parameters to train logistic model on training set and test on testing set. Relevant logs and figs will be generated.

6. POST /cnn_model/train:

   {
       "cell_number": 16,
       "choice": "linear_count",
        "height": 50,
       "learning_rate": 0.0001,
       "number": 1000,
       "patience": 5000,
       "train_set_file": "train",
       "width": 50
   }

   Pass some parameters to train cnn model on training set. Other parameters include patience and learning_rate can also be modified to increase training efficiency and model performance. Logging will be displayed in folder ~/static/models/cnn_model.

7. POST /cnn_model/test:

   {
       "test_set_file": "test",
       "params_path": "linear_count_params",
       "choice": "linear_count"
   }

   Pass some parameters to test cnn model on testing. params_path stands for path of params, choice stands for which final layer and output we are using. Available choice are linear_count/logistic_count/logistic_zeroOne. Logging will be displayed in folder ~/static/models/cnn_model.
