## Dataset

### Agriculture-Vision Challenge Dataset

  

  

The dataset used in this challenge is a subset of the [Agriculture-Vision dataset](https://arxiv.org/abs/2001.01306). The challenge dataset contains 21,061 aerial farmland images captured throughout 2019 across the US. Each image consists of four 512x512 color channels, which are RGB and Near Infra-red (NIR). Each image also has a boundary map and a mask. The boundary map indicates the region of the farmland, and the mask indicates valid pixels in the image. Regions outside of either the boundary map or the mask are not evaluated.

This dataset contains six types of annotations: Cloud shadow, Double plant, Planter skip, Standing Water, Waterway and Weed cluster. These types of field anomalies have great impacts on the potential yield of farmlands, therefore it is extremely important to accurately locate them. In the Agriculture-Vision dataset, these six patterns are stored separately as binary masks due to potential overlaps between patterns. Users are free to decide how to use these annotations.

Each field image has a file name in the format of (**field id**)_(**x1**)-(**y1**)-(**x2**)-(**y2**).(**jpg**/**png**). Each field id uniquely identifies the farmland that the image is cropped from, and (x1, y1, x2, y2) is a 4-tuple indicating the position in which the image is cropped. Please refer to our paper for more details regarding how we construct the dataset.

### Download

The challenge dataset contains images, boundaries and masks for train, val and test set. It also contains labels for the train and val set only. The 2021 new dataset .tar.gz file is around 20 GB. Please visit [our website](https://www.agriculture-vision.com/agriculture-vision-2021/dataset-2021) or [our huggingface page](https://huggingface.co/datasets/shi-labs/Agriculture-Vision) to get access. By downloading or using the dataset, user signifies its agreement to [Agriculture-Vision Workshop Terms and Conditions](https://drive.google.com/file/d/1tiJpMjcr8mlF1pYU-6U6ZY5jnNgbn9XF/view?usp=sharing). 

## Evaluation

### Evaluation metric

We use mean Intersection-over-Union (mIoU) as our main quantitative evaluation metric, which is one of the most commonly used measures in semantic segmentation datasets. The mIoU is computed as:



Where **c** is the number of annotation types (**c** = 7 in our dataset, with 6 patterns + background), P_c and T_c are the predicted mask and ground truth mask of class c respectively.

Since our annotations may overlap, we modify the canonical mIoU metric to accommodate this property. For pixels with multiple labels, a prediction of either label will be counted as a correct pixel classification for that label, and a prediction that does not contain any ground truth labels will be counted as an incorrect classification for all ground truth labels.

Concretely, we construct the confusion matrix **M^c×c** with the following rules:

For each prediction x and label set Y:

1. If **x** ∈ **Y**, then **M_y,y** = **M_y,y** + 1 for each **y** in **Y**


2. Otherwise, **M_x,y** = **M_x,y** + 1 for each **y** in **Y**


The mIoU is finally computed by (**true_positive**) / (**prediction** + **target** - **true_positive**), averaged across all classes.

### Submission

**Update:**

* The 1st Agriculture-Vision Prize Challenge has ended on April 20, 2020 (10:00 AM PDT). The final results as of the end date of the challenge can be found in these links ([png](https://github.com/SHI-Labs/Agriculture-Vision/raw/master/codalab_challenge_results.png), [csv](https://raw.githubusercontent.com/SHI-Labs/Agriculture-Vision/master/codalab_challenge_results.csv)).

* The Codalab evaluation server will remain open to encourage further research in Agriculture-Vision. No registration is required.

#### Registration

We are now hosting our evaluation/competition on **Codalab**. The competition page can be found [here](https://competitions.codalab.org/competitions/23732?secret_key=dba10d3a-a676-4c44-9acf-b45dc92c5fcf). Each participating team is required to register for the challenge. To register your team, fill out the registration form here, then register on the competition page.

*Make sure your Codalab account email matches one of the member emails in the registration form. Each team can only register once.

#### Codalab submission

All registered teams can evaluate their results on Codalab and publish their results on the leaderboard. The submission file should be a compressed **.zip** file that contains all prediction images. All prediction images should be in **png** format and the file names and image sizes should match the input images exactly. The prediction images will be converted to a 2D numpy array with the following code:

`numpy.array(PIL.Image.open(‘field-id_x1-y1-x2-y2.png’))`

In the loaded numpy array, only 0-6 integer labels are allowed, and they represent the annotations in the following way:

0 - **background**


1 - **cloud_shadow**


2 - **double_plant**


3 - **planter_skip**


4 - **standing_water**


5 - **waterway**


6 - **weed_cluster**


This label order will be strictly followed during evaluation.

All teams can have 2 submissions per day and 20 submissions in total.

## Challenge

We hosted the 1st Agriculture-Vision Prize Challenge with the following terms:

- Model size will be limited below 150M parameters in total.

- The mIoU derived from the "results/" folder in the final submission should match the mIoU on the leaderboard.

- Predictions in "results/" in the final submission can be reproduced with the resources in "code/" and "models/".

- The training process of the method can be reproduced and the retrained model should have a similar performance.

- The test set is off-limits in training.

- For fairness, teams need to specify what public datasets are used for training/pre-training their models in their challenge_ report.pdf. Results that are generated from models using private datasets, and results without such details will be excluded from prize evaluation. (Results using private datasets can still be included in the report.)

The prize award will be granted to the top 3 teams on the prize challenge leaderboard (closed on 4/20/2020) that provide a valid final submission.

### Paper Track

- We accept papers related to Agriculture-Vision with a rigorous peer-review process with program committee members from  multiple research communities including computer vision, machine learning, image processing, remote sensing, agriculture etc.

- All accepted paper will be published in IEEE CVPR 2020 Workshop Proceedings. 

- Several top accepted papers will be given oral presentation opportunity at our workshop, the rest accepted papers will be given poster presentation slots during the workshop.

#### Topic Description

The Workshop will be open to the broader community addressing **various technical and application aspects of challenges and opportunities in computer vision research for agriculture.** We aim to provide a venue to both show current relevant efforts in interdisciplinary areas between computer vision and agriculture, and to encourage further research and conversations within the computer vision community to tackle impactful agriculture-vision problems. We will solicit papers from the following wide range of topics:

- Computer vision research for agricultural imagery in general

- Resources and benchmarks for agricultural imagery based pattern analysis

- Farmland pattern classification and segmentation from LSHR aerial imagery
