We are pleased to introduce the Qilin Watermelon Dataset, a unique collection of data aimed at investigating the relationship between a watermelon's appearance, tapping sound, and sweetness. This dataset is the result of our dedicated efforts to capture and record various aspects of Qilin watermelons, a special variety known for its exceptional taste and quality.

Our dataset consists of two primary components: wav files and jpg files. The wav files contain audio recordings of the tapping sounds produced when striking the watermelons with varying degrees of force. These recordings capture the acoustic properties of the watermelons, which may provide insights into their internal structure and ripeness. Alongside the audio files, we have also included jpg files that showcase the external appearance of each watermelon. These images encompass various visual characteristics, such as color, texture, and shape, which may contribute to the overall assessment of the watermelon's quality.

To ensure the accuracy and reliability of our dataset, we employed a rigorous data collection process. We used a sugar meter to measure the sweetness of each watermelon, providing a quantitative value that can be correlated with the tapping sounds and visual appearance. By recording the sweetness levels, we aim to establish a comprehensive understanding of how these factors interplay and potentially influence the watermelon's taste.




Qilin Watermelon Dataset Structure


The Qilin Watermelon Dataset is structured in a way that facilitates easy understanding and usage. The dataset consists of two main directories: "picture" and "audio", which contain the original data files, and a processed data directory named "chu".


In the dataset, each file follows a naming convention that includes an underscore symbol ("_"). The part before the underscore represents the unique identifier or serial number of the watermelon sample, while the part after the underscore indicates the sweetness measurement obtained using a sugar meter.


For example, a file named "001_12.jpg" would represent the image of watermelon sample number 001, which has a sweetness measurement of 12 according to the sugar meter.


The "picture" directory contains the jpg files showcasing the external appearance of each watermelon, capturing visual characteristics such as color, texture, and shape. These images can be used for visual analysis and feature extraction.


The "audio" directory contains the wav files capturing the tapping sounds produced when striking the watermelons with varying degrees of force. These audio recordings can be used to analyze the acoustic properties of the watermelons and potentially correlate them with the sweetness measurements.


In addition to the original data, the dataset also includes a "chu" directory, which contains processed data. This directory is intended for users who prefer to work with pre-processed data or want to compare their processing techniques with the provided processed files.


If you are unsure about how to use or navigate the Qilin Watermelon Dataset, you can refer to the GitHub repository at https://github.com/crf0409/watermelon_eval. This repository contains code examples and explanations that can guide you through the process of loading, processing, and analyzing the dataset.


By understanding the structure and naming convention of the Qilin Watermelon Dataset, you can easily access and utilize the data for your research or analysis related to watermelon quality assessment.
