FAQ About AI Upscaling Images
How Can I Improve the Resolution of a Picture?
The most effective way to enhance the resolution of an image is to use a dedicated software tool that can increase the number of pixels used maintaining the picture's integrity. Such tools are known as image upscalers or photo enhancers.
What Does it Mean to Upscale an Image?
Scaling is simply resizing a digital picture in a proportional way. Upscaling, as you probably guessed, means to enlarge/enhance an image, to make it look bigger and better. Image upscaling can take a low-resolution photo and turn it into a high-resolution, even a super-resolution one.
How Does AI Upscale an Image?
Traditional digital upscaling was about stretching out a low-res image and then copying and repeating the pixels to fill out the holes in a larger display. While added technology such as filters is used, the results can still be blurry or noisy.
AI image upscaling is a whole other and incredibly better story. Instead of stretching out the image, it uses trained neural networks to actually predict what the image would look like in a higher resolution, and produce a very high-end result with optimal sharpness and zero blurs.
