PIXELL AI:
Deep Learning based
Image Quality Enhancement and upscaling

Our deep learning AI model, trained on tens of thousands of ultra-high-definition videos, demonstrates the most advanced level of image enhancement performance.

Model Training

 & Advancement

4BY4's team of image quality experts who has been collaborating with leading global display companies to set and define the standards for 'optimal image quality' team up with top-class AI researchers. Together, they train and refine models to produce the best results. The quality data provision and continuous feedback from image quality experts on output videos, along with various research and experiments by the internal AI researchers, enables a faster and more precise enhancement of solutions.

PIXELL AI
Deep Learning based Image Quality Enhancement and upscaling

The technology optimizes each element that constitutes image quality, such as noise, sharpness, and color, to achieve the closest possible quality to human vision. 

Our deep learning AI models, trained on tens of thousands of ultra-high-definition videos, demonstrates the most advanced level of image enhancement performance.

Dominant

Performance

Compared to existing image enhancement AI models, PIXELL AI demonstrates overwhelming performance differences across all areas that determine image quality: saturation, contrast, noise, and sharpness.

Depending on the features of the original source video and the degree of quality degradation, a comprehensive process is undertaken, including upscaling, noise reduction, color enhancement, sharpness improvement, and brightness adjustment, to achieve results that closely resemble what is seen with the naked eye.

Scientific Recognition

Through collaborative research with PIXELL Lab, the Graduate School of Advanced Imaging Science at Chung-Ang University (AI Graduate School), and the AI startup AI Nation, we continuously enhance our core technologies in the field of image quality AI. We are strengthening our tech leadership by submitting papers to prestigious academic journals and filing patents.
