# Shear Augmentation

Randomly distort an image across its horizontal or vertical axis. This adds variability to perspective to help your model be more resilient to camera and subject pitch and yaw.

* Horizontal: Select the highest amount an image will be randomly sheared across its x-axis.
* Vertical: Select the highest amount an image will be randomly sheared across its y-axis.
