| ## Contents | |
| - 905 samples (test: 135, train: 632, val: 138); one image and one label per sample. | |
| - `images/*.png`: 16-bit grayscale PNG, intensities in [0, 65535] map linearly to [0, 1]. | |
| - `labels/`: binary channel masks (NPY, C x H x W). Label ids/channels: | |
| - channel `0`: background | |
| - channel `1`: ilium | |
| - channel `2`: pubis | |
| - channel `3`: ischium | |
| - channel `4`: femoral_head | |
| - channel `5`: femur | |
| - `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/MTDDH | |
| ``` | |
