Finding Berries: Segmentation and Counting of Cranberries using Point Supervision and Shape Priors

PyTorch implementation of the paper. (09/22/2021: Important to note that this code is quite old at this point, and may have conflicts and/or dependencies of older CUDA versions. I made a recent update to the code which runs successfuly on an RTX3090, CUDA 11.1, PyTorch 3.9, however experiences may vary)

Dataset

We use the CRAID (CRanberry Aerial Imagery Dataset) in our experiments. The dataset can be downloaded from:

• CRAID

Setting up the environment

We can set up an environment in 2 ways: locally, or in a docker container.

Locally

We use Python 3.6. We recommend using Anaconda (Available here) to manage and install libraries. Once anaconda is installed, run those commands:

git clone [email protected]:periakiva/finding_berries.git
cd finding_berries
conda create --name finding_berries --file environment.yml
conda activate finding_berries
python setup.py develop

Evaluation on a fully-supervised test dataset

First edit all parameters in the config file under .configs/segEval.yaml

Then run

python evaluate.py

Evaluation on a given images

run

python forward_pass_on_single_image.py --image_path <path to image or directory> --save <Optional, path to directory to save output, if saving is needed>

Training from scratch

First edit all parameters in the config file under .configs/craid.yaml

Then run

python train_eval.py

Docker

This project can also be ran in a docker container. First install docker and nvidia-docker on your machine (docker, docker-nvidia). Then:

git clone [email protected]:periakiva/finding_berries.git
cd finding_berries
mkdir data
cd data
mkdir checkpoints
cd checkpoints
wget --load-cookies /tmp/cookies.txt "https://docs.google.com/uc?export=download&confirm=$(wget --quiet --save-cookies /tmp/cookies.txt --keep-session-cookies --no-check-certificate 'https://docs.google.com/uc?export=download&id=1Y1FxmQmiypD145I327G8o82EgAL_q2eo' -O- | sed -rn 's/.*confirm=([0-9A-Za-z_]+).*/\1\n/p')&id=1Y1FxmQmiypD145I327G8o82EgAL_q2eo" -O floodfill_epoch_43_mean_iou_0.6254406128186686_best_mae_13.459821428571429_mioumao_ratio_4.646722960908185_time_2020-03-09-13:23:56.pth && rm -rf /tmp/cookies.txt

Download and save data to the data direcotory. The data should be in 2 or 3 directories (depending on functionality): images, masks, back-masks. Generally, only the images and masks directories are necessary where masks have both berry and background points.

sudo docker build -t finding_berries .
sudo docker run --gpus all -it -p80:3000 finding_berries

Then you can run any of the scripts on the docker container. Note that you will need to set up the config file with respect to which approach you use. Sample config file can be seen below.

In the case you use

Usage

In order to run this code, adjustments should be made to the config file in training and evaluation code. Sample config file:

# Ours

location: docker #[local, docker]
data:
  image_size: 456x608 # size of image. if image size is different than this, need to train from scratch, and not use pretrained model.
  local:
    type: semantic_seg # type of dataset to use. [semantic_seg,instance_seg,points]
    model_save_dir: /path/to/directory/where/model/is/saved
    train_dir: /path/to/train/data/
    test_dir: /path/to/test/data/
    val_dir: /path/to/val/data/
  docker:
    type: semantic_seg
    model_save_dir: /app/finding_berries/models/
    train_dir: /app/finding_berries/data/instance_points/
    test_dir: /app/finding_berries/data/semantic_seg/
    val_dir:
  
training: 
  learning_rate: 0.001 
  resume: False # if true, insert path to the model to be resumed. Otherwise this will train from scratch

  train_val_test_split: [0.9,0.05,0.05] #split of the data
  epochs: 200
  batch_size: 1 # what batch size to use
  optimizer: adam # which optimizer to use
  num_workers: # number of workers

  loss_weights: {seg: 3.0, instance: 3.0, convexity: 10.0, circularity: 10.0, count: 0.2}
  class_weights: {seg: [1,3,'mean'], instance: [6,1,'mean']}

  losses_to_use: ["instance","circularity", "count_detect"]
  test_with_full_supervision: 1

use_cuda: True

After config file is modified, simply run the train/evaluate script that is in the same directory. Some paths might be coded into the script, so error may occur. TODO: this should be fixed in the docker approach
