| Abstract: | Image fusion is the process of extracting meaningful visual information from two or more images and combining them to form one fused image. Image fusion is important within many different image processing fields from remote sensing to medical applications. In various real life applications, such as medical image diagnosis, image fusion plays important role. Because of undefined nature of practical imaging systems the capture images or acquired images are corrupted from different types of noises hence fusion of image is an integrated approach where reduction of noise and retaining the original features of image is essential. Here the input to fusion involves set of images taken from different modalities of the same scene; Output is a better quality image. Image fusion is important within many different image processing fields from remote sensing to medical applications. Combining of two different modality images using wavelet transform and various fusion rules to fuse CT and MRI images. This method gives encouraging results in terms of greater entropy. The DWT(Discrete wavelet Transform) technique uses three methods of fusion i.e Maximum Selection Method, Average Selection Method and Minimum Selection Method. Of these three methods the Maximum Selection Method gives greater entropy. PCA(Principal Component Analysis) technique is one of the most widely used techniques for dimension reduction, image fusion, feature identification, pattern recognition.The PCA technique gives the greater entropy value when compared to DWT and is one of more efficient technique. |
