Medical images fusion using two-stage combined model DWT and DCT

The purpose of image enhancement is to improve the interpretation or perception information in for viewers and input automated processing systems. Combining a multicenter way combining several images on screen, focusing different objects so that all appear focus final image. Wavelet transform cosine are used many applications, including fusion. This paper's technique will combine DWT DCT two steps medical MRI PET images, eventually extracting combined Input first divided into 8-pixel blocks which coefficients extracted. After coefficients, step combination takes place. re-images then be with conversion. According presented data, proposed method achieved up 5% better and, as result, quality than single-stage methods.
