Fusion of Image Using Higher Order Singular Value Decomposition

Image processing is a method to convert an image into digital form and perform some operations on it, in order to get an enhanced image or to extract some useful information from it. It is a type of signal dispensation in which input is image, like video frame or photograph and output may be image or characteristics associated with that image. Usually Image processing system includes treating images as two dimensional signals while applying already set signal processing methods to them. Image fusion is the process by which the information from two or more images are combined together to make resulting image more appropriate and effective. In this work important visual information with the "edge" information which is present in each pixel of an image is associated. Human visual system supports this visual to edge information and uses it in image analysis and compression systems. Keywords— Tensor, Higher Order Singular Value Decomposition, Sigmoid.
