The 21st century,people’s lives becusc of technological progress,has undergene tremendous chaneges The health problem as long been the focut of attention.If the doctor in the meubation period of the lesion,through the orgaration of minor changes,can accurately detect the lesion and can make the disese in a timely manner.the treatment of patients is very usefulThis poper introduces the background and research significance of medical image proessing technology and the methods,principles and related function expressions of medical image cnhancement echnolgy,and comparev the advantegees and disadvantages of medical image proccssing technolop.With the help of MATLAB to get the invervrse,gray seale sdjustment,loganthmic trariformration,Gammu(gamma)transformtion,bistogram equalization,pseudo color processing and tharpering niter after the operation of medical images,The medical images of Prewin operator,Sobel cpratot and Laplacian operator are compared.The cmphashs is on the improvement of medical image bewed on Lapaciam operator,and the and the original image plus the image processed by the filter is analyzed,and the effece of the improved image an the edge of the image is analyzedIn this paper,the image preptoccssing system is designed under the GUI interface of MATLAB,compared wth similar systems,its running interface is simple and smooth,and itis designed to tei the imprved medical image enhancert effeet.The system includes file opcration.basic cnhancement,took and ocher modus,and bricfly describes the design ideas and functions of the system module.Based on the histogram reflecting the rrlationship between the gray level and the pixel,the preset system conpared with the medical mago before after the impprovement.After the image reversed the logarithmic transformation.the Gamma transform,the median filter after the image enhancement effect.According to the histogram in a spccific range of pixel changes,more accurate inerprctstion of the inugc edge enhincement effect.The design of the cao rotage the image,cut and other operations.help doctors interpret the image.Finally,the design of the image enhancement processing is put forward,and the improvement direction is put forward.The medical image enhancement processing system designed in this paper is running smoothly,and it can reduce the time of medical diagnosis in the practical application.After comparing the histogram of the improved image,the quality of the medical image has been improved greatly,The edges and contours of the image are also enhanced.The design of the system will be medical image processing related technology into the same interface,shortening the doctor to analyze the time of medical images,improve work efficiency and reduce the difficulty of image processing operations.
