ABSTRACT
Many areas of photography and imaging use Depth of Field (DoF) as an aesthetic component, choosing to selectively keep areas in focus or out of focus. Very early attempts to increase DoF before the advent of digital cameras and scanners were more hardware-based. Another technique to get enhanced DoF images involved creating an image-capture apparatus. Once computing caught up with digital imaging technology, some very high-quality but computationally intensive and expensive techniques became available. Image stitching is a process where two or more images are combined to increase the area imaged by using a camera system differently. There are two primary categories image stitching typically fall into: image mapping or panorama. Both types of stitching use the same basic type of image-processing function of pattern recognition and mapping to find common edges and details in a series of images in order to seamlessly splice them together to extend the scene.
