Gaussian blur is mathematically reversible, but in practice you don't have enough resolution to successfully deconvolve the original image. However in the case of video you have multiple images and you can reconstruct a "super-resolution" image by combining frames. I'm sure there is a tool somewhere that can do this, there are too many secrets being shown blurred on TV to pass ...

- kevin_thibedeau 9y agoIf the original image had high frequency edges such as a matrix code or text then it can still get you close enough to decode the deconvolved result.
