Face blurring

blur_faces=1

blur_faces=TH,R,S,CR

For censorship or privacy, you can use the blur_faces filter which will fog all faces found in the image by applying Gaussian blur.

Example

Available options

If you are unsure which settings you should use, you can start with default values (blur_faces=1).

Face blurring is most effective for images with enough spatial resolution and sufficiently high quality. For example, for crowd shots, the recommended size is at least 800 pixels.
