In the 90’s Photoshop was getting off the ground but Macromedia had the good stuff, Flash, Fireworks… If you did sites and were in the job market, Flash was a must. It all evolved, companies created their own products, but Photoshop was most widely used. There’s talk about Google’s new pixel unscrambler, incorporating a process which has been used for years.
Guardian: “Google’s neural networks have achieved the dream of CSI viewers everywhere: the company has revealed a new AI system capable of “enhancing” an eight-pixel square image, increasing the resolution 16-fold and effectively restoring lost data.
The neural network could be used to increase the resolution of blurred or pixelated faces, in a way previously thought impossible; a similar system was demonstrated for enhancing images of bedrooms, again creating a 32×32 pixel image from an 8×8 one.”
In simple terms, the process looks at a blurred image, defines what/how it is blurred, and separates that as best as possible from the original image. All along that image is being compared to others on file in an effort to match/ID.
The tech term for encrypting with pixelation is mosaicing (query it and get a better understanding of everything).
