Benchmark Evaluation of Image Fusion algorithms for Smartphone Camera Capture
Lucas N. Kirsten

TL;DR
This study evaluates various image fusion algorithms for smartphone cameras, analyzing their trade-offs in image quality, computational resources, and runtime to identify optimal configurations for constrained environments.
Contribution
It provides a comprehensive benchmark of image fusion methods, highlighting the effects of different parameters and proposing best practices for resource-efficient smartphone imaging.

Increasing input frames does not necessarily enhance image quality and increases resource use.
Abstract
This paper investigates the trade-off between computational resource utilization and image quality in the context of image fusion techniques for smartphone camera capture. The study explores various combinations of fusion methods, fusion weights, number of frames, and stacking (a.k.a. merging) techniques using a proprietary dataset of images captured with Motorola smartphones. The objective was to identify optimal configurations that balance computational efficiency with image quality. Our results indicate that multi-scale methods and their single-scale fusion counterparts return similar image quality measures and runtime, but single-scale ones have lower memory usage. Furthermore, we identified that fusion methods operating in the YUV color space yield better performance in terms of image quality, resource utilization, and runtime. The study also shows that fusion weights have an…
