Not true unless you know beforehand the exact kernel. Besides, there's 0 reason why a camera software be programmed to, or attempt to revert Gaussian blur.
And finally, he downsampled the image, and you can't recover from that.
- geoduck14 4y agoIsn't a gaussian blur a pretty standard blur done by a poorly focused camera? Perhaps Samsung went to great lengths to reverse a Gaussian blur because it happens all the time?
- toxik 4y agoGaussian blur is indeed super common in nature, any sum of noise will be Gaussian in the limit.

- Jasper_ 4y agoNo, a real camera would give you a box blur, because the out-of-focus light rays are distributed uniformly across the sensor.
