The LostAndFound Dataset addresses the problem of detecting unexpected small obstacles on the road often caused by lost cargo.

The dataset comprises 112 stereo video sequences with 2104 annotated frames (picking roughly every tenth frame from the recorded data).

If you are using this dataset in a publication please cite the following paper:

For the data format and the interpretation of the data sources we refer to the description of the Cityscapes dataset format which we closely follow: http://www.cityscapes-dataset.com

Below you can find a link to the data description and some development kit (tailored for Cityscapes but applicable to LostAndFound as well):


In order to replace the cityscapes mapping with lostAndFound labels replace labels.py in the development kit with this file: labels.py

A description of the labels of the LostAndFound dataset can be found here: laf_table.pdf
