  The Stixel World is a medium-level, compact representation of road scenes
that abstracts millions of disparity pixels into hundreds or thousands of
stixels. The goal of this work is to implement and evaluate a complete
multi-stixel estimation pipeline on an embedded, energy-efficient,
GPU-accelerated device. This work presents a full GPU-accelerated
implementation of stixel estimation that produces reliable results at 26 frames
per second (real-time) on the Tegra X1 for disparity images of 1024x440 pixels
and stixel widths of 5 pixels, and achieves more than 400 frames per second on
a high-end Titan X GPU card.
