Nice and clean. However, it looks like the blur has some (blue?) banding artifacts in it. Am I the only one who sees that?

- ihuman 7y agoI see it too. I wonder if it's including the blue border you see in one of the earlier debugging images.
- snovv_crash 7y agoHah, yes, I guess they're doing the blurring on the image with the box overlaid, instead of the original.
- cbhl 7y agoYes, I would also guess they're blurring the image with the box overlaid. In a production implementation, you may also want to consider how you do edge handling here. (For faces in the middle of the frame, you want to use the real pixels from the underlying source image? Do you want to extend the pixels from inside the border? What are the aesthetic and information theory implications of each technique?) https://en.wikipedia.org/wiki/Kernel_(image_processing)#Edge_Handling https://en.wikipedia.org/wiki/Kernel_(image_processing)#Edge...
