Chromatic spikes

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

Dataset Details

Description

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, 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:

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

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/.
