# OCTScenes: A Versatile Real-World Dataset of Tabletop Scenes for Object-Centric Learning
|

|
| 17 |
-
This is the official dataset of OCTScenes (https://arxiv.org/abs//2306.09682). OCTScenes contains 5000 tabletop scenes with a total of 15 everyday objects. Each scene is captured in 60 frames covering a 360-degree perspective.

-
In the OCTScenes-A dataset, the 0--3099 scenes without segmentation annotation are for training, while the 3100--3199 scenes with segmentation annotation can be used for testing. In the OCTScenes-B dataset, the 0--4899 scenes without segmentation annotation are for training, while the 4900--4999 scenes with segmentation annotation can be used for testing.

This folder contains scenes with 128x128 resolutions. The name of each image is in the form `[scene_id]_[frame_id].png`. The images are compressed using `tar`, and the name of compressed files starts with the resolutions, such as 'image_128x128_'. Due to the large capacity of scene images, all are packaged into two parts and uploaded, namely image_128x128_00 and image_128x128_01. Please download all the compressed files, and use 'tar' instruction to decompress the files.

For example, please download all the scene files starts with 'image_128x128_*', and then merge files into 'image_128x128.tar.gz':
|
| 24 |
-
|
| 25 |
-
```
|
| 26 |
-
cat image_128x128_* > image_128x128.tar.gz
|
| 27 |
-
```
|
| 28 |
-
|
| 29 |
-
And then decompress the file:
|
| 30 |
-
|
| 31 |
-
```
|
| 32 |
-
tar xvzf image_128x128.tar.gz
|
| 33 |
-
```
|
| 34 |
-
|
| 35 |
-
Download the segmentation annotations from `./128x128/segments_128.tar.gz`. We provide the segmentations of test scenes 3100-3199 for OCTScenes-A and 4900-4999 for OCTScenes-B. Each segmentation annotation image is named as `[scene_id]_[frame_id].png`. The int number in each pixel represents the index of the object (ranges from 1 to 10, and 0 represents the background).
