The conventional in radiography is used film radiography and the newest is used filmless radiography or called digital radiography. The image processing is widely used in radiography to increase the quality of the image as well as to help the interpreter in analyzing welding discontinuity. The aim of this study is to develop analyzing tool to identify the welding discontinuities on welded part captured by digital radiography X-ray machine (ndt analyzer) at FKM's lab. The acquiring image will be improved using this analyzing tool so called "Advanced Defect Analyzer Tool (ADAT)". The results of using the AD AT will indicate the improvement image quality in shows the clear defect region and identify correct types of welding discontinuities. One of the advantages of ADAT is user friendly by providing the variable options of processing image for the user to observe the region of image. ADAT is fully developed using MATLAB 7.5(R2007b). In a first stage, image processing techniques, including noise reduction, contrast enhancement, and edge detection were investigated to help recognizing the weld discontinuity region of the specimen. For the second stage, the Graphical User Interface (GUI) was developed by compiling all the image processing methods.
