Available options
| parameter | description | default value | description |
|---|---|---|---|
| TH | threshold of the face detection algorithm | 0.15 | threshold of the face detection algorithm |
| R | blur radius | 30 | |
| S | blur sigma (Gaussian distribution) | 1000 | |
| CR | corner radius of the masking shape (use max for an ellipse) | 0 | corner radius of the masking shape use max for an ellipse |
If you are unsure which settings you should use, you can start with default values (blur_faces=1). The filter is turned off by omitting it or using blur_faces=0.
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.
