Performance Evaluation and Comparison of Service-based Image Processing based on Software Rendering

Wegen, Ole; Trapp, Matthias; Döllner, Jürgen; Pasewaldt, Sebastian in 27th International Conference in Central Europe on Computer Graphics, Visualization and Computer Vision (WSCG 2019) 2019 .

This paper presents an approach and performance evaluation of performing service-based image processing using software rendering implemented using Mesa3D. Due to recent advances in cloud computing technology (with respect to both, hardware and software) as well as increased demands of image processing and analysis techniques, often within an eco-system of devices, it is feasible to research and quantify the impact of service-based approaches in this domain with respect to cost-performance relation. For it, we provide a performance comparison for service-based processing using GPU-accelerated and software rendering.
