Cat Dataset

### Context

The CAT dataset includes over 9,000 cat images. For each image, there are annotations of the head of cat with nine points, two for eyes, one for mouth, and six for ears.

### Content

The annotation data are stored in a file with the name of the corresponding image plus ."cat" at the end. There is one annotation file for each cat image. For each annotation file, the annotation data are stored in the following sequence:

- Number of points (default is 9)
- Left Eye
- Right Eye
- Mouth
- Left Ear-1
- Left Ear-2
- Left Ear-3
- Right Ear-1
- Right Ear-2
-Right Ear-3

### 背景信息
CAT数据集囊括了超过9,000张猫的图片。针对每张图片，均附有猫头部九点标注，其中双眼各两点，口部一点，耳朵六点。

### 数据内容
标注数据存储于与对应图片同名的文件中，文件扩展名为".cat"。每张猫图片对应一个标注文件。对于每个标注文件，标注数据按照以下顺序存储：
- 点数数量（默认为9）
- 左眼
- 右眼
- 嘴部
- 左耳-1
- 左耳-2
- 左耳-3
- 右耳-1
- 右耳-2
- 右耳-3
