FUSION OF MEDICAL IMAGES USING TRANSFORM TECHNIQUES

Mamatha M, Padmavathi N.B.


Medical image fusion is a method in which the information from many images of the same picture are registered and combined into single fused image, which provides more information, compared to each single source image and it provides more reliable result for the observers. Image fusion techniques are performed here using Discrete Wavelet transform, Contourlet transform and Curvelet transform. The fusion performance is evaluated on the basis of Peak Signal to Noise Ratio (PSNR), Structural Content (SC), Normalized Absolute Error (NAE) and Standard Deviation (SD).
