Model and recognition of currency attribute based on multivariate normal distribution
Xuesong Xu · Systems Engineering - Theory & Practice · 2010
Based on the theory of multivariate normal distribution,a novel way to evaluate the effective and precise sensors used in currency recognition is proposed.The model of currency attribute is built and used to save the information of currency attribute by storing the parameter of probability function,which can decreases the memory for storing information and improve the speed of searching.It has considered all the information that the sensors gains and reduced the dimension effect.So this way has a broadly value for the study of currency property and the selection of recognition method.
