MLCAS 2019 - Sorghum head detection

Welcome to the MLCAS 2019 - Sorghum head detection challenge.  This challenge is a part of Second International Workshop on Machine Learning for Cyber-Agricultural Systems (MLCAS 2019). The challenge aims at identifying new approaches to advance the state-of-the-art in Sorghum head detection from UAV images. The detection of sorghum heads from crop row images will be useful in estimating yield of the crops. More details about the wokshop could be found at https://www.register.extension.iastate.edu/mlcas2019/about.

Data Description

This challenge uses RGB image frames of Sorghum heads collected from an UAV. The dataset consists of 1300 images wth sorghum head annotations. You can find further information about the datasets for Training phase and Final test phase in the "Participate" tab under the heading "Get Data". The datasets could be downloaded from  the "Participate" tab under the heading "Files". The training dataset contains both labelled images and  unlabelled images. Participants are encouraged to use algorithms from active learning, semi-supervised learning or unsupervised learning for utilizing the unlabelled images during training.

Annotation Format

The images in the training and validation sets are provided with annotations that indicate the bounding box for each object. The names of the ground truth text files match the names of their corresponding input images. Each line of the ground truth label file contains the classname, left top  and bottom right coordinates of the bounding box.  The first pixel at left top of the image is considered to be coordinate (0,0). The annotation file format is <class_name> <left> <top> <right> <bottom>. For example, the ground truth text file of he input image C1-R15-G13-DSC00677.jpeg is

"C1-R15-G13-DSC00677.txt"

sorghumHeadyieldTrail 4 214 28 238
sorghumHeadyieldTrail 4 268 21 292

Submission Format

  • Create a separate detection text file for each input test image.
  • The names of the detection files must match their corresponding input images (e.g. "C1-R12-missing-DSC00877.txt" represents the detections corresponding to C1-R12-missing-DSC00877.jpeg").
  • In these files each line should be in the following format: <class_name> <confidence> <left> <top> <right> <bottom>.
  • E.x. "C1-R12-missing-DSC00877.txt":
sorghumHeadyieldTrail 0.769319 12 682 34 700
sorghumHeadyieldTrail 0.907736 13 972 39 999
sorghumHeadyieldTrail 0.449279 14 1069 40 1094
sorghumHeadyieldTrail 0.124237 16 1122 63 1140
sorghumHeadyieldTrail 0.535341 17 742 52 780
  • A zip folder containing all the detection text files should be submmited for evaluation.

Prize

The top three winning teams will receive travel grants as listed below (in addition to waiver of registration fees). Students and early career researchers (within five years of receiving their terminal degree) are eligible for the awards. Note that the amounts listed below are for the whole team, not individual participants. Also, in order to be eligible for the award, at least one team member needs to attend the award ceremony on September 11 and present the team’s work on September 12 at MLCAS 2019.

1st prize  $1500

2nd prize $1200

3rd prize  $1000
