As v0.7 slowly stabilises I’m kicking off the tutorial series with a look at de-noising Radiance images generated with LiVi.

Blender has a nice image de-noising capability that can be used quite effectively with Radiance images. De-noising does not replace higher accuracy analyses – ‘Low’ accuracy settings will still generally produce overall lower luminance and illuminance values, especially in interior scenes – but this is a nice trick to get cleaner images with reduced simulation time.

Comparison between the original rpict image and it’s de-noised version
