WebDevelopment of the Curve of Spee It is assumed that the deciduous denti-tion has a COS ranging from flat to mild. The COS depth is minimal in the deci-duous dentition (flat), its greatest increase occurs in the early mixed dentition as a result of permanent first molar and central incisor eruption; it maintains this depth WebOct 31, 2016 · The development of a computer-aided diagnosis (CAD) system for differentiation between benign and malignant mammographic masses is a challenging task due to the use of extensive pre- and post-processing steps and ineffective features set.
