This is the dataset for **Real-data-driven 2000 FPS Color Video from Mosaicked Chromatic Spikes**.

## Dataset Details

### Description

<!-- Provide a longer summary of what this dataset is. -->

This is the public dataset containing more than 100 chromatic spike streams, captured by a spike camera equipped with Bayer-pattern color filter array.
Each stream can be represented as an uint8 array with shape [T, H, W], where T is the number of spike frames, H and W are height and width (1000 and 1000 for this dataset).
Spike streams are saved with [**tensorstore**](https://google.github.io/tensorstore/), which is a library for efficiently reading and writing large multi-dimensional arrays.
To load the spike streams, please first extract tar files and refer to the following example script:

```python
import numpy as np
import tensorstore as ts

dataset_dir = "tensorstore/20230922113135162"

dataset = ts.open(
  {
    "driver": "zarr3",
    "kvstore": {
      "driver": "file",
      "path": dataset_dir,
    },
  }
).result()

print(dataset.shape)  # => (20000, 1000, 1000)
print(dataset.dtype)  # => dtype("uint8")
print(np.unique(dataset[:100].read().result()))  # => [0 1]
```

## Structure

<!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->

The dataset contains more than 100 chromatic spike streams, each is saved as a tensorstore array and further archived to a tar file.
The tar files are placed in `/tensorstore/`.

## Citation

<!-- If there is a paper or blog post introducing the dataset, the APA and Bibtex information for that should go in this section. -->
