In the past, when we encountered some particularly poor-quality, small-resolution or blurry pictures and wanted to make them larger and clearer, our first thought was to use tools such as Adobe Photoshop and GIMP to enlarge and sharpen the image. But the results are mostly unsatisfactory. Because the enlarged image is either full of mosaics or blurred, or loses a lot of details. Now, the development of AI technology is also revolutionizing the image processing technology.

As a matter of fact, lossless compression is not very difficult for image files. With proper algorithms, you can compress the file size of an image while preserving as much detail as possible. On the contrary, it is very difficult to enlarge images without quality loss. As everyone knows, image is made up of pixels, and it becomes blurry and distorted when you zoom in on it. If we want to realize the lossless magnification of an image, we need to make up for the missing details after the image enlargement, which has a very high requirement on the calculation and analysis capabilities of program.
