LayeredFlow-Syn Extracted Ground Truth
This repository contains viewer-friendly extracted LayeredFlow ground-truth annotations in Parquet format.
Layout
data/<scene>/<sample>.parquet
For example:
data/0/0_0.parquet
Each Parquet file stores one sample as one row. Image columns are grouped in this
order: frame0/left, frame0/right, frame1/left, then frame1/right. Within each
group, saved per-file optical-flow visualization PNGs come first. For example,
frame0_left_flow_layer00_forward_visualization.png is loaded from
frame0/left/flow_layer00_forward_visualization.png, which visualizes
frame0/left/flow_layer00_forward.flo.
Mask and position PNG ground-truth assets are recorded in the png_files metadata
column with relative paths, byte sizes, and SHA-256 checksums. They are not embedded as
viewer image columns by default because Hugging Face previews 100 rows at a time; the
full 80-image-column table is too large for the dataset-viewer worker. JSON files are
stored in the json_files metadata column. Flow .flo files are represented in
flow_files with their relative paths, byte sizes, and SHA-256 checksums; they are not
embedded as raw binary viewer cells because Hugging Face cannot preview raw .flo
binaries.
Converted selector 29 contains 546 samples,
16 flow visualization image columns, and
64 extracted PNG ground-truth files.
