Abstract: Image enhancement is the pre-processing stage of the image processing. The objective is to improve the visual effects and the perception of knowledge in images for viewers and to provide a better input for automated image processing technique. It gives emphasis on the whole or part features of the graphics in the designated image applications to enlarge the objects in the graphics. The enhanced image by use of threshold segmentation method identifies bone fracture in medical X-ray images. In this research work, the image is taken as input and after noise removal, the X-ray image of right hand and hairline bone fracture image is being segmented using simple thresholding, multiple thresholding and optimal thresholding method and compared with each other so as to choose the best technique for threshold image segmentation.
Keywords: medical images; bone x-rays; image segmentation; optimal thresholding; image representation; image enhancement; image processing; bone fractures; hand fractures; hairline fractures; simple thresholding; multiple thresholding.
