- W2386161259 abstract "Homomorphic filter and histogram equalization can enhance the image individually,but they still have many disadvantages.In view of the disadvantages,a new algorithm which combines homomorphic filtering with histogram equalization in frequency domain is presented.Firstly,X-ray images are processed separately by using homomorphic filter.Then,the low frequency components are processed with global histogram equalization.Finally,the high frequency components and the low frequency components are linear fusion.The experimental results show that the boundary of X-ray images is very prominent and evident,and the overall visual effect is more bright and clear.Root mean square error and signal to noise ratio data are obtained by analysis,which confirmed that the methods can enhance X-ray images effectively." @default.
