Comparison of Spatial Domain and Transformation Domain Image Fusion Technique for Restoration of Blur Images

Pixel level image fusion can be performed in spatial and transformation domain. In this paper we describe two image fusion techniques, transformation domain technique i.e. Wavelet based image fusion technique and spatial domain technique i.e. Principle component analysis.
Both these techniques are compared by calculating Spatial Frequency Root mean square error and Peak signal to noise ratio. Results shows that transformation domain technique gives better results than spatial domain technique.
