Evaluation of model performance for trajectory estimation based on line segment detection, using the TbD Easy 30 dataset subset. Key metrics include average error, standard deviation of error, and runtime.

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 | Trajectory Estimation via Line Segment Detection |
| Dataset (including any stated split) | TbD Easy 30 |
| Metric | Average Error (px) |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 8 of 8 |
| 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

- [Average Error (px)](<https://www.sota2.com/research/sota/trajectory-estimation-via-line-segment-detection-on-tbd-easy-30.md?metric=Average%20Error%20(px)>): Lower is better; unit: SCALAR.

- [Standard Deviation Error (px)](<https://www.sota2.com/research/sota/trajectory-estimation-via-line-segment-detection-on-tbd-easy-30.md?metric=Standard%20Deviation%20Error%20(px)>): Lower is better; unit: SCALAR.

- [Runtime (secs)](<https://www.sota2.com/research/sota/trajectory-estimation-via-line-segment-detection-on-tbd-easy-30.md?metric=Runtime%20(secs)>): Lower is better; unit: TIME.
