Images are a part and parcel of our life and an extremely essential component of advertising and marketing campaigns. Often people are more disposed to trusting visual content as compared to the written one, hence it becomes necessary to optimize one’s images so that it can be presented manifestly clear.
If you tried to take a low-resolution image and enlarge it (increase its size) you will realize that the output image is almost certainly distorted and blurry. The reason behind this is that the images have fewer pixels that make it difficult to reproduce all the fine and minute details that were present in the original image. The only solution to this is the process of Upscaling an image.
Upscaling involves enlarging an image with its resolution without any loss in the quality of the image. Due to this the, image can be presented in comparatively large formats such as HDTV displays, big screens and more. By increasing the resolution of the image, you can ensure that the quality of the image improves simultaneously that makes it appear like the original even in large sizes.
Image upscaling is best carried out by AI based applications in which the AI algorithm compares the two frames, fills (interpolates) the gap between them by producing new pixels of picture information using machine learning and building a high-resolution image. This new high-resolution image, when downscaled would appear to look like the original source image.
In this article we will be exploring 3 Free AI based Image Upscalers that are based on Stable Diffusion.
