A Theory On Image Fusion Techniques

Due to imperfections of imaging device and instability of the observed scene (object motion, media turbulence),
acquired images are often blurred, noisy and may exhibit insufficient spatial and/or temporal resolution. Such images are not
suitable for object detection and recognition. Reliable detection requires recovering the original image. If multiple images of the
same scene are available, this can be achieved by image fusion. Image fusion is the process by which two or more images are
combined into a single image retaining the important features from each of the original images. In this paper we focus on the
detailed theory of different fusion techniques.
