Abstract: This paper proposes a new B-spline & median filte based on human vision system.This algorithm fully considers the characteristics of humanity visual characteristic to detect the noise pixel，the filter window size is adaptively adjusted according to the window size，uses the b_spline function and median filter to estimate noise pixels.This paper produces the experiments and the result analysis.This algorithm can effectively remove noises and also retain image details very well.It also provides a new way for image filtering.
