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/.
