Abstract

Morphological Image Processing is an important tool in digital image processing based on human intuition and perception. The morphology is based on the geometry, which emphasizes the geometry of the image. The morphology of the process is mainly used to remove the imperfections that exist in the form of an image. No exception in the field of medicine/medical, often obtained results Rontgen or scanning of the resulting images do not have the accuracy of the expected image quality. This is because of factors of body movement or instrument (not focusing) so that the resulting image is blurred and distorted. One method is to enhance this image by using morphology method. With operations of erosion and dilation as well as a combination of both in the process of opening and closing, the morphology of high level/complex projects could be implemented. The key to success lies in the selection process of the morphology of mathematical operations and the choice of structured elements. Even the selection of filters and methods of transformation in this process is often not used. In this study optimal results are obtained for the distorted image with SNR of 19.891 dB, reduction bits of 2.206, and Gain of 13.27 dB.
