| ## Contents | |
| - 139 samples (test: 21, train: 97, val: 21); one image and one label per sample. | |
| - `images/*.png`: 16-bit grayscale PNG, intensities in [0, 65535] map linearly to [0, 1]. | |
| - `labels/`: dense index map (PNG). Label ids/channels: | |
| - `0`: background | |
| - `1`: femurs | |
| - `2`: hips | |
| - `dataset.yml`: `fxr-dataset` manifest (schema version 1). Splits are the | |
| ones used in the FleXray paper; `metadata.original_shape` is the source image shape. | |
| ## Preprocessing | |
| Every image was min-max normalized to [0, 1] per image, padded to a square with zeros | |
| (centered) and resized to 256 x 256 (area interpolation for images, nearest for labels). Labels were remapped from the | |
| source annotation to the dataset-native names listed above; the FleXray package maps | |
| those names into its label protocol at training time. | |
| ## Usage | |
| ```bash | |
| pip install flexray | |
| fxr-dataset validate dataset.yml | |
| fxr-dataset pack dataset.yml /data/flexray/HipRay | |
| ``` | |
