Construction of Harmonic Low Pass Filter
Constructs the harmonic low pass filter transfer function H(u,v),the function has the properties of continuity,positive,passes through endpoints and non-incremental.Through experimental analysis,the low pass filter has significant results in the image de-noising processing,the filter compared with the traditional low pass filter,it has a simple structure,good filtering effect and suitable for all kinds of noise,etc.The filter can meet the requirements of different image processing through modifying the value of n.
