# Dataset Card for Mechanized Soybean Harvest Quality Image Dataset
This dataset contains images captured during the mechanized harvesting of soybeans, aimed at facilitating the development of machine vision and deep learning models for quality analysis. It contains information of original soybean pictures in different forms, labels of whether the soybean belongs to training, validation, or testing datasets, segmentation class of soybean pictures in one dataset.

## Dataset Description
The dataset comprises 40 original images of harvested soybeans, which were further augmented to 800 images through various transformations such as scaling, rotating, flipping, filtering, and noise addition. The images were captured on October 9, 2018, at the soybean experimental field of Liangfeng Grain and Cotton Planting Professional Cooperative in Liangshan, Shandong, China. This collection is intended for use in the development of online detection models for soybean quality during mechanization processes.

## Dataset Sources
The images were obtained using an industrial camera during the mechanized harvesting process and subsequently annotated by experts in the field.

## Uses
The dataset is designed for:
Developing online detection models for soybean quality.
Analyzing soybean mechanization processes.
Training deep learning algorithms for image classification and feature extraction.

## Out-of-Scope Use
The dataset should not be employed for non-agricultural applications or outside the context of soybean quality detection during mechanization.

## Original Dataset Structure
The dataset is structured into three main folders:
JPEGImages: Contains 800 JPG images of soybeans.
SegmentationClass: Contains PNG images with annotations.
ImageSets: Contains TXT records for data partitioning.

## Data Collection and Processing
The main goal is to combine all the files into a single dataset with the following columns:
unique_id: str. unique id for each picture
sets: str. Categorical. Contains records for data partitioning (test/train/valid)
original_image: contains path to 800 JPG images of soybeans.
segmentation_image: contains path to PNG images with annotations.

## Curation Rationale
The creation of this dataset was motivated by the need for making a standardized dataset that reflects the real conditions of mechanized soybean harvesting for use in quality detection research.

## Annotation Process
Field experts annotated the dataset, manually labeling different components of the soybean images using polygonal annotations.
Bias, Risks, and Limitations
The dataset is limited to a specific soybean variety and harvesting environment, which may affect its generalizability. Future expansions are planned to include more diversity.

## Recommendations
Users should follow ethical guidelines for handling data and consider the dataset's limitations when interpreting results from their models.
