In an era where images are increasingly important, having a model capable of generating ultra-high-resolution images is a blessing for designers and creators alike. UltraPixel is just such a black tech marvel.
Firstly, it supports the direct generation of images with resolutions ranging from 1K to 6K. Imagine any image, finely detailed down to the pores, with crystal-clear clarity. The demonstration images are even more impressive, with details seamlessly added without any awkwardness, leaving viewers in awe.
The secret behind UltraPixel lies in its training and fine-tuning based on the Stable cascade, and it is soon to be open sourced, allowing everyone to experience the charm of this technology firsthand.
In the later stage of noise reduction, this model guides the generation of high-resolution images by utilizing rich semantic information from low-resolution images. In other words, it simplifies complex tasks, significantly reducing the complexity of generating high-resolution images.
In addition, it proposes an implicit neural representation for continuous upsampling, and introduces a scale-aware normalization layer that adapts to different resolutions. The application of these technical means ensures that images maintain a high degree of detail and realism during the processing from low to high resolution.
Even more astonishing is that both low-resolution and high-resolution processing are done in the smallest possible space. The two processes share most of the parameters, with the additional parameters required for high-resolution output being less than 3%. This means that UltraPixel not only generates ultra-high-resolution images but also greatly improves the efficiency of training and inference.
