depth-anything-v2

This repository hosts Depth Anything V2 Small (ViT-S/14) exported for React Native ExecuTorch as ExecuTorch .pte programs for on-device relative depth estimation.

Upstream model: depth-anything/Depth-Anything-V2-Small-hf, revision 5426e4f0f36572d16453bbda7a8389317b1bef99.

XNNPACK int8

The INT8 export uses dynamic INT8 activations and per-channel INT8 weights for linear layers; convolutions remain floating point. Public inputs and outputs remain float32.

Numerical agreement with the float reference on four held-out upstream example illustrations (demo17–demo20):

Image	Range-normalized RMSE	Correlation
demo17	1.24%	0.999633
demo18	1.34%	0.999104
demo19	0.47%	0.999970
demo20	1.28%	0.999690

Range-normalized RMSE is RMSE divided by the reference depth range. These are numerical export checks, not depth-accuracy benchmarks. A synthetic random-input check reached 3.32% range-normalized RMSE (correlation 0.990703).
