Title:

Image Stitching Techniques-An overview

Author:
 Ms. Vrushali S. Sakharkar and Prof. Dr. S. R. Gupta
 
Abstract

In this paper, we describe various Image stitching techniques used to combine multiple images together to make a wide angle picture called Panorama. Algorithms for stitching and aligning have many applications in computer vision like texture synthesis, object recognition, medical imaging. Images of any object or place are acquired using 360. rotating camera and the overlapped portion of images  should  be aligned properly. Image stitching requires identical exposures to produce seamless results. It is also known as mosaicing. Stitching can be done into three stages Acquisition, Remapping, Blending. We have described different techniques for all the stages.  Image acquisition can be done using rotating camera, translating camera and hand held camera. Image Remapping involves Alignment, conversion of camera image to Sphere, Selection of final projection, Exposure setting. Image remapping is also called Warping. The final warped images should blend perfectly so the visible seams   between the images can be removed. Image blending techniques like Average Blending, Alpha Blending, Feathering, Pyramid blending used to remove Exposure difference, Blurring, Ghosting. Finally unwanted information can be cropped using various cropping techniques like graph cuts, gradient blending etc.
