Evaluation of 2D Neural Image Alignment (Homography) performance on the 'cat' subset of the ImageNet dataset, measured using Corner error (pixels) and Patch PSNR.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | 2D Neural Image Alignment (Homography) |
| Dataset (including any stated split) | ImageNet cat |
| Metric | Corner Error (pixels) |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Corner Error (pixels)](<https://www.sota2.com/research/sota/2d-neural-image-alignment-homography-on-imagenet-cat.md?metric=Corner%20Error%20(pixels)>): Lower is better; unit: SCALAR.

- [Patch PSNR](<https://www.sota2.com/research/sota/2d-neural-image-alignment-homography-on-imagenet-cat.md?metric=Patch%20PSNR>): Higher is better; unit: SCALAR.
