The Best Free AI Solutions of Lossless Image Upscaling

Part 1: What Is AI Upscaling

What Is Basic Upscaling?

Basic upscaling is the simplest way of stretching a lower resolution image onto a larger display. Pixels from the lower resolution image are copied and repeated to fill out all the pixels of the higher resolution display. Filtering is applied to smooth the image and round out unwanted jagged edges that may become visible due to the stretching. The result is an image that fits on a 4K display, but can often appear muted or blurry.

And What Is AI Upscaling?

Traditional upscaling starts with a low-resolution image and tries to improve its visual quality at higher resolutions. AI upscaling takes a different approach: Given a low-resolution image, a deep learning model predicts a high-resolution image that would downscale to look like the low-resolution image.

To predict the upscaled images with high accuracy, a neural network model must be trained on countless images. The deployed AI model can then take low-resolution image and produce incredible sharpness and enhanced details no traditional scaler can recreate. Edges look sharper, hair looks scruffier and landscapes pop with striking clarity.

How does AI upscale image?

Al upscaling involves creating new pixels of image information to add detail where there wasn’t any before, filling in the gaps to recreate a higher-resolution image, all the while using machine learning to improve the result.

Part 4: Other Traditional Way to Upscale Image

Normally, we are used to applying Photoshop to process the photo. And recently Adobe has added one of the useful technology into photoshop, which is the new algorithm for scaling images up: Preserve Details 2.0

How To Upscale Images With Preserve Details 2.0

Open the image you want to enlarge in Photoshop.
Make Sure "Preserve Details 2.0" Is Enabled.
Even though Preserve Details 2.0 is included with Photoshop CC 2018, it's not officially part of Photoshop just yet. Adobe considers it a technology preview, and to use it, we need to make sure it's enabled. We do that in the Photoshop Preferences. On a Windows PC, go up to the Edit menu in the Menu Bar. On a Mac, go up to the Photoshop CC menu. From there, choose Preferences, and then choose Technology Previews and make sure Enable Preserve Details 2.0 Upscale is selected.
Open Photoshop's Image Size dialog box by going up to the Image menu and choosing Image Size. In the preview area, click and drag the bottom right corner of the Image Size dialog box outward to make it larger
In the resizing options along the right, make sure Resample is selected.
By default, the resampling method is set to Automatic. This means that Photoshop will automatically choose the best algorithm for the job. Click on it and choose Preserve Details 2.0.
Click OK and preview the result.

As you can see from the image the new method makes for a much better image compared to the traditional bicubic smoother interpolation. But compared with AI upscaler, the AI image upscaler gets the best result.

Conclusion

So how about the result of AI image upscaling VS Traditional image upscaling?
Although we have had the traditional way to upscale images, it always requires a manual operation to keep its visual quality at higher resolutions. While AI image upscaling is much more automatic by using a deep learning model to analyze the image and fill the missing pixels and get the best quality. So you can easily make an image upscaling to 2x, 4x, with an AI upscaler. All becomes simple and easy. Just try your image to evaluate the power of AI.
