Abstract
Currently, Chest X-ray is still widely used around the world for disease examination. This is due to its low cost, low radiation and a lot of disease information. The commonly detected disease using chest x-rays is lung disease. The characteristic of this disease is infiltrate. However, the accuracy of Chest X-ray observations is still low. Therefore, this research offers a method to perform Chest X-ray image processing in clarifying the information contained therein.This research used Chest X-ray of infant patients who treated at Central Public Hospital (RSUP) Dr. M. Djamil Padang. The total of the images tested were 17 images. In these images, there were some suspected infiltrates after being analyzed by doctors. Software used was Matlab which is conducted by applying image processing method. The method used consisted of 4 parts, that was Cropping, Filtering, Detecting Edge, and Sharpening Edge. The results of the research showed that the method could clarify edge detection of the objects contained in the image, so that the infiltrate could be more easily recognized. With this easiness, it will help the doctor to remove doubts for infiltrate observations in the Infant's lungs.

1.Introduction
One of medical image is chest x-ray. Chest x-rays offer simplicity, low cost, low radiation, lots of information, and worldwide availability.. The purpose of the chest x-ray use was to prove the doctor's perception in identifying lung disease [1]. Characteristics of patient infants who suffer from lung disease were installed with respiratory aids.
Figure 1 shows, infants who were suspected from lung diseases, in which respiratory aids were installed for both of them. Figure 1(a) is the CPAP in nose and Figure 1(b) is the Ventilator in mouth. The existence of infiltrate in the lungs indicates the presence of disease in the patient's lungs. Infiltrate is an abnormal pulmonary feature that can be seen at Chest X-Ray image [2]. There are white patches in the image [3]. These white patches can be liquid or dense. The types of diseases that can cause infiltrates are tuberculosis or pulmonary [4].
Infiltrate on radiographic images can be only analyzed by experts such as radiologist or...
