SAPPHIRE middleware and software development kit for medical video analysis

This paper presents SAPPHIRE - a novel middleware and software development kit, developed to reduce implementation efforts in utilizing task parallelism to speed up execution time of analysis of a stream of data, such as medical video. As a case study, we implemented a real-time quality measurement of colonoscopy using SAPPHIRE. We increased the number of threads in our case study from 4 (prior to our middleware) to 28 with ease. As a result, through better load-balancing and taking better advantage of available processor cores, we increased the case study´s maximum processing rate from 40 frames per second to 90 frames per second.
