WebNov 2, 2024 · The photoplethysmography (PPG) signal contains various information that is related to CVD (cardiovascular disease). The remote PPG (rPPG) is a method that can measure a PPG signal using a face image taken with a camera, without a PPG device. Deep learning-based rPPG methods can be classified into three main categories. First, there is … WebReflection depends on the type of wave, the wave’s frequency, and the material. Absorption happens when a wave loses energy as it transmits into a material. This can happen in a medium or at a boundary between two materials. When a wave is absorbed by a material, its energy turns into another form of energy, such as thermal or electrical energy.
