Profile/Element(Histogram)

• P_rk：is the grayscale of pixels grade；

• n： is the number of rows of gray matrix； • m：is the number of columns in the grayscale matrix ；

Polynomial Function

•

  The exponential function (in blue), and the sum of the first n+1 terms of its Maclaurin power series (in red)

Correlation Analysis

• i=(1,2,.....n) • Linear regression curve transformation • The coefficient range -1 to 1, 1 has a good correlation, 0 has no linear correlation, -1 inverse correlation;
