Image processing for NDT images

The fusion of images is the process of combining two or more images into a single image retaining important features from each. Image fusion is an important technique especially in nondestructive method of testing [1 – 3] wherein no damage is done to the material being tested. There are two categories of image fusion, one being fusion of images from the same sensor and the other being multi - sensor image fusion. Many methods of fusion have been developed such as Wavelet based image fusion and Dempster - Shafer method of fusion. This work contemplates on which technique works better giving better end results using performance metrics. It has been observed that a particular method cannot be termed as the best method for image fusion as it has been seen that it depends on the conditions of the image, thus the need to judiciously select the best method for the given source images.
