Spring: A High-Resolution High-Detail Dataset and Benchmark for Scene Flow, Optical Flow and Stereo

The Spring dataset contains files for scene flow, optical flow and stereo estimation.
For easier handling, we organized them into sub-directories:
</br>
<i>train</i> split:
<ul>
<li><code>train_frame_left.zip</code>: left camera frames</li>
<li><code>train_frame_right.zip</code>: right camera frames</li>
<li><code>train_disp1_left.zip</code>: left-to-right disparity in the reference frame</li>
<li><code>train_disp1_right.zip</code>: right-to-left disparity in the reference frame</li>
<li><code>train_disp2_FW_left.zip</code>: left-to-right disparity in the future/forward target frame</li>
<li><code>train_disp2_BW_left.zip</code>: left-to-right disparity in the past/backward target frame</li>
<li><code>train_disp2_FW_right.zip</code>: right-to-left disparity in the future/forward target frame</li>
<li><code>train_disp2_BW_right.zip</code>: right-to-left disparity in the past/backward target frame</li>
<li><code>train_flow_FW_left.zip</code>: left forward optical flow</li>
<li><code>train_flow_BW_left.zip</code>: left backward optical flow</li>
<li><code>train_flow_FW_right.zip</code>: right forward optical flow</li>
<li><code>train_flow_BW_right.zip</code>: right backward optical flow</li>
<li><code>train_cam_data.zip</code>: camera data: intrinsics, extrinsics, focal distance</li>
<li><code>train_maps.zip</code>: additional maps: detail, match, rigid, sky</li>
</ul>
<i>test</i> split:
<ul>
<li><code>test_frame_left.zip</code>: left camera frames</li>
<li><code>test_frame_right.zip</code>: right camera frames</li>
<li><code>test_cam_data.zip</code>: camera data: intrinsics</li>
</ul>
</br>
File formats:
<ul>
<li>images and maps are given in png format</li>
<li>optical flow files are given in HDF5 file format and named <code>.flo5</code></li>
<li>disparity files are given in HDF5 file format and named <code>.dsp5</code></li>
</ul>
