Medical Image Stitching Using Hybrid Of Sift & Surf Techniques

Abstract — Image stitching is a technique that combines two or more images from the same scene to obtain a panoramic image. Image stitching is used in Medical system for stitching of X-ray images. As the flat panel of X-ray system cannot cover all the parts of a body. So stitching of Medical images can be done. Stitching of images basically includes two main parts – Image Matching and Image Blending. For Image Matching the two algorithms SIFT and SURF are used. This paper presents a technique using hybrid of SIFT and SURF. As SIFT is slow process and not suitable at illumination changes while it is invariant to scale changes, rotation and affine transformations whereas SURF is having illumination property and having high computational speed. So by combining both methods, a new method can be generated that creates panoramic image having better features
