S1: ET(1h30,E,sd,sc) x2 + CC(CR TP) x1;
S2: ET(20m,O,sd,sc) x2 + Rep(CC) x1 Detail of the nomenclature used for the creation of the evaluation code
This class deals with multi-rate systems. Such systems consider signals at several sampling frequencies (multi-resolution). They can be seen nowadays in various application, such as the now weel known JPEG2000 norm, which is based on wavelet decomposition. The gaussian pyramid is another exemple of a multi-rate approach that improves the robustness of image analysis systems. Those approaches share the common base of the digital signal theory and linear filtering.
