Exploring Foveation Techniques for Virtual Reality Environments

Virtual reality technology is constantly advancing leading to the creation of novel experiences for the user. High-resolution displays often are accompanied by higher processing power needs. Foveated rendering is a potential solution to circumvent this issue as it can significantly reduce the computational load by rendering only the area where the user is looking with higher detail. In this work, we compare different foveated rendering algorithms in terms of the quality of the final rendered image. The focus of this work is on evaluating 4K images. These algorithms are also compared based on computational models of human visual processing. Our analysis revealed that the non-linear content-aware algorithm performs best.
