Linear Transformation: Preserves linear relationship between variables. Therefore, correlation between x and y would be unchanged after a linear transformation. Nonlinear Transformation: Changes linear relationship between variables, and thus, changes the correlation between variables.

What is a nonlinear transformation?
A nonlinear transformation changes (increases or decreases) linear relationships between variables and, thus, changes the correlation between variables. Examples of a nonlinear transformation of variable x would be taking the square root of x or the reciprocal of x.
What is linear transformation?
A linear transformation is a function from one vector space to another that respects the underlying (linear) structure of each vector space. A linear transformation is also known as a linear operator or map.

LINEAR TRANSFORMATION
A linear transformation changes the original variable x into the new variable xnew given by an equation of the form. xnew = a + bx. Adding the constant a shifts all values of x upward or downward by the same amount. Multiplying by the positive constant b changes the size of the unit of measurement ...
What is non-linear transformation in image processing?
A novel non-linear transformation for sharpening digitized gray-level images is defined. The transformation replaces the gray level value at a point by either the minimum or the maximum of gray levels in its neighborhood, the choice depending on which one is closer in value to the original gray level.
