Image enhancement based on the Bernstein harmonic function
Zhaohong Li · Journal of Science of Teachers' College and University · 2011
Bernstein harmonic function was first introduced in digital image enhancement processing,constructed a class of nonlinear transformation by using of the positive properties,endpoint properties and weighted properties of Bernstein harmonic function.This class nonlinear transformation can reach all sorts of digital image enhancement purpose and requirements by selecting frequency of function and adjusting the gray-scale controls parameters.It is flexible,controllable and easy to modify.The examples shown that the image enhancement effect is extremely effective through.
