# Blur Augmentation
Add random Gaussian blur to make your model more resilient to variations in camera focus.
Add random Gaussian blur to help your model be more resilient to camera focus.
* Pixels: Determines the amount of blur applied to an image (i.e. the kernel size of the blurring process; all kernel sizes are odd). 25 pixels is max blur.
