Wearable devices have become increasingly popular in the last years. Among them, mixed-reality headset displays (HSDs) represent the most critical device for several application fields. Indeed, they must provide users with immersive experiences of the real world through displays with high-resolution and high refresh rate and must be comfortable to be worn. Meeting such requirements is not trivial and custom energy efficient architectures for the video processing pipeline are needed. In this work, we evaluate the performance of an approximate foveated-based Super-Resolution method for image upscaling. Preliminary results show that the proposed approach allows significantly reducing the number of operations with respect to the prior art, without introducing detrimental effects on the perceptual visual quality.

Abstract
Wearable devices have become increasingly popular in the last years. Among them, mixed-reality headset displays (HSDs) represent the most critical device for several application fields. Indeed, they must provide users with immersive experiences of the real world through displays with high-resolution and high refresh rate and must be comfortable to be worn. Meeting such requirements is not trivial and custom energy efficient architectures for the video processing pipeline are needed. In this work, we evaluate the performance of an approximate foveated-based Super-Resolution method for image upscaling. Preliminary results show that the proposed approach allows significantly reducing the number of operations with respect to the prior art, without introducing detrimental effects on the perceptual visual quality.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
