Many companies are using AI for image creation that can generate a realistic, detailed photo from scratch in minutes. This includes applications such as DALL-E and Stable Diffusion that have been around for the past few months. This blogpost explains why Viesus is so valuable in this process.
To demonstrate let's take our hero image, the Matterhorn during sunrise, from the landing page as an example. We use DiffusionBee for Mac which implemented the Stable Diffusion model. In this example, we want the Matterhorn sunrise image to be painted in Van Gogh style. Therefore, I enter the prompt with what we want to generate and I selected the original Matterhorn sunrise image. You can fine-tune options, but for now I'll start with the default option. The generation is ready in a minute!
The current limitations of these generative AI models for images is the low resolution. That means the generated image soon looks blurry. The resolution is 512x320 pixels at the moment. It can be enlarged to 1024x640 but that does not improve the quality. It probably looks fine on your mobile phone, but displaying it larger could be problematic. For example, if we want this generated AI image to be a printed canvas on the wall.
One thing you can do to increase the quality of your images is to use AI Upscaling. Viesus has created a feature that combines these types of upscaling algorithms together, like Super Resolution. You won't have to compromise on your images with any blurring - these algorithms are designed for high resolution and true quality. In this example, for convenience, we are going to enlarge our image by 4x from 512 × 320px to 2048 × 1280px.
The comparison between the original and upscaled versions demonstrates that even though it might not be immediately obvious on screen, there are a lot of nuanced differences in the look of the two renderings. However, in the field that we operate, this difference is huge. When a person wants to hang this "Van Gogh Matterhorn" as a large print on the wall of their home, high quality is required to avoid disappointment.
That's why our customers say AI Upscaling is an absolute must-have for AI-generated images and more companies want to use it.
