Description

Industry currently relies on manual inspection of X-Ray images, which is expensive, time consuming and subject to inconsistent results by various inspectors. Automatic inspection of the industrial NDE images using high speed computers would make the flaw detection task more consistent and efficient. However, since the objects to be inspected usually have complex geometric structures, it is very difficult to separate automatically flaws from the complex geometric background of an image. Most of the automated inspection systems developed so far are customized packages which are tailored for particular types of applications, such as the inspections of aluminum wheel castings [1], the welds of space shuttle fuel tanks [2], and nodules in chest X-rays [3]. Customized packages have the advantages of relatively fast speed and good liability, but they can not be used in other applications without substantial changes in computer programs.
