 | `device`      | `str`   | `None`  | Specifies the device for validation (`cpu`, `cuda:0`, etc.). Allows flexibility in utilizing CPU or GPU resources.                                                                                                                    |
 | `dnn`         | `bool`  | `False` | If `True`, uses the [OpenCV](https://www.ultralytics.com/glossary/opencv) DNN module for ONNX model inference, offering an alternative to [PyTorch](https://www.ultralytics.com/glossary/pytorch) inference methods.                  |
 | `plots`       | `bool`  | `False` | When set to `True`, generates and saves plots of predictions versus ground truth for visual evaluation of the model's performance.                                                                                                    |
-| `rect`        | `bool`  | `False` | If `True`, uses rectangular inference for batching, reducing padding and potentially increasing speed and efficiency.                                                                                                                 |

 | `split`       | `str`   | `val`   | Determines the dataset split to use for validation (`val`, `test`, or `train`). Allows flexibility in choosing the data segment for performance evaluation.                                                                           |
