Datasets

CVPR2016 Sequences

We provide here the datasets which have been used in our work [1] for comparison and evaluation. The scenes are taken by a moving DVS camera (rotation+translation) and contain moving objects to highlight the capabilities of our method. All sequences have been taken with the same bias setting for the event camera (see below). The events are provided in a binary-format, which is described below.

	Face sequence Recommended start time: 3.15s
	Ball sequence Recommended start time: 4.15s
	Jumping sequence Recommended start time: 4.8s
	HDR sequence Recommended start time: 4.15s NOTE: Scene contains a monitor with low refresh rate, which causes many events to fire.

Format

The events are sequentially stored in a binary file. Each event is encoded into 8 bytes, where the first 4 bytes stores the absolute time-stamp in microseconds and the last 4 bytes stores the event-polarity (1 for positive, 0 for negative) and the x and y position in the image. The latter bytes can be processed by using the the following bit-masks:

image_position_x = data & 0x000001FF

image_position_y = (data & 0x0001FE00) >> 9

polarity = (data & 0x00020000) >> 17,

where data is an integer, which contains the last 4 bytes of an event.

DVS128 Biases

A detailed description of the biases can be found on the iniLabs website. We use the same bias settings as used in the jAER project.
