What is IRIS

This chapter describes efficient visual analysis methods towards the unobtrusive monitoring of elderly people using common low-cost hardware. In particular, two real-time approaches are demonstrated for (a) Pupil Size Estimation and (b) Pulse Rate Estimation. In both cases, a main concern in the development has been to keep low the overall complexity, so that the hosting hardware that executes the proposed methods is left with free resources, in order to be able to also execute other processes in the context of a health monitoring framework. In addition, all experiments have been carried out using typical, low-cost visual sensors, i.e. simple webcams. Finally, the respective benchmarks needed to evaluate the two methodologies are described in this chapter.
