X-ray Medical Image Enhancement Based on Improved Homomorphic Filtering
Jiang Yuzhe · Journal of Henan Normal University · 2014
In this paper,an enhancement method based on X-ray medical image is presented.It combines characteristics of X-ray image with the advantage of homomorphic filtering enhancement,puts forward a hnomomorphic filter based on the frequency field fo X-ray medical image,and carries out the filtering control by giving the position and coefficient of maximum gain.The medium-high frequency is amplified properly without lessening the low frequency signal.The important organization edge and texture can be strengthened the flimsy grey and texture information in the dark area is kept well.Experimental results show that the algorithm has low distortion and high operational efficiency,it is feasible and achieves nice enhancement result for X-ray medical image.
