Abstract :
The defect of existing fidelity definition is discussed, by using this definition, it is found that two obviously different image can be determined to be approximate or the same. According to the defect, an improved fidelity definition is presented. The difference and relation between the two definitions are discussed and the analytic expression for deriving one definition from the other is also presented
