# Dataset Card for "NTU-Stem"

![sample](sample.png)

The NTU Tree Dataset is a high-resolution few-shot learning dataset of the stem images of 15 different tree species found in the National Taiwan University (NTU) campus. The dataset was collected using personal cellphones in an effort to increase familiarity with the campus’s natural beauty.

The dataset includes images of the stem of the following 15 tree species, along with their Chinese and English names:

| 中文名稱     | English Name             |
|--------------|--------------------------|
| 大王椰子     | Royal Palm               |
| 土肉桂       | Indigenous Cinnamon Tree |
| 大葉桃花心木 | Honduras Mahogany        |
| 小葉南洋杉   | Araucaria Excelsa        |
| 石栗         | Indian Walnut            |
| 朴樹         | Chinese Hackberry        |
| 血桐         | Macaranga                |
| 垂榕         | White Barkfig            |
| 肯氏南洋杉   | Hoop Pine                |
| 美人樹       | Floss-silk Tree          |
| 烏桕         | Chinese Tallow Tree      |
| 楓香         | Formosan Sweet Gum       |
| 榕樹         | Marabutan                |
| 蒲葵         | Chinese Fan Palm         |
| 樟樹         | Comphor Tree             |

The dataset contains a total of 240 images, with each species class containing 8 to 16 training images and the remaining 8 to 10 images serving as test data. The images were captured at a resolution of approximately 3k x 3k pixels, providing high detail for the purpose of few-shot learning.
