Panoramic image stitching is the process of combining multiple photographic images with overlapping fields of view to produce a panorama. First, salient features are robustly detected from the input images by a robust algorithm called Scale Invariant Feature Transform ...

This paper presents an effective method in panoramic image creation. Here an automatic method of feature detection and feature mating using SIFT (Scale Invariant feature transform) algorithm has been used. SIFT algorithm is very robust method that can detect and describe local features in the image. Then find the overlapping area of these two images. A minimal cost path in the overlapping area of two images is found by dynamic programming method. This minimal-cost path (optimal seam) is used to stitch images. Dynamic programming is faster than other seam finding methods and uses little memory. The overlapping images are cut along the seam and merge together. Here there are seven steps used in image stitching which include: input image, feature detection, feature matching, image registration, computing homography using RANSAC, image warping, and finally image labeling using optimal seam.

In this paper, we have described the basic methods used to generate panorama image. Our objective is to provide different methods and algorithms used to generate panoramic image. This paper is mainly for the new comers who want to do work in the field of image mosaicing.
An innovative method for stitching the images for panoramic view
An image stitching method panorama gives serious issues with respect to distortion when collaborating long similar sequential images. To solve the distortion enhanced approach is proposed in this work, adding the alteration of the way sequential referred image and adding a head an approach that can calculate the transformation matrix[3] for any image with in the sequence to put for alignment[11] with the referred image with in the same space of coordinate area. Apart from this the enhanced stitching approach selects the next preceding image automatically based on the matched output points with respect to number of SIFT[10] approach. With regular stitching methodology and enhanced stitching[8] methodology , by comparing these two our approach decreases the SIFT features ROI detected area of the referred image. Our practical results shows theenhanced approach cannotonly initiate the efficiency of stitching on image processing and also drastic reduction of thepanoramic distortion[10][14] issues. This resu lts the plain non distorted panoramic image output.
Panoramic mosaics by manifold projection
cvpr, 1997
As the field of view of a picture is much smaller than our own visual field of view, it is common to paste together several pictures to create a panoramic mosaic having a larger field of view. Images with a wider field of view can be generated by using fish-eye lens, or panoramic mosaics can be created by special devices which rotate around the camera's optical center (Quicktime VR, Surround Video), or by aligning, and pasting, frames in a video sequence to a single reference frame. Existing mosaicing methods have strong limitations on imaging conditions, and distortions are common.
A REVIEW OF IMAGE MOSAICING METHODS
Image Mosaicing is the process of combining two or more images of the same scene into one image and generate panorama of high resolution image. In this paper, we have described the basic methods used to generate panorama image. Our objective is to provide different methods and algorithms used to generate panoramic image. Mosaicing is one of the techniques of image processing which is useful for tiling digital images. Mosaicing is blending together of several arbitrarily shaped images to form one large radiometrically balanced image so that the boundaries between the original images are not seen. The output of image mosaic will be the union of two input images. In this paper we present a review on different approaches for image mosaicing.
Optimization and Alignment of Multiple Images to Construct a Panoramic Images
With The Prevalence Of Smart Phones, Sharing Photos Has Become Popular. Since Cameras Generally Have A Limited field Of View, Panoramic Shooting Mode Is Provided, Where The User Can Capture Images Under Guidance To Generate A Panorama. Panorama Fused Image Will Be Help The User To View The Wide Angle Image. But Still Panorama Images Are Not Homogenous And It Affects Viewing Experience. If Panorama Images Can Be Brought Homogenous, It Reconstructed Image Is Of Good Clarity. In This Project We Solve The Problem Of Getting Good Quality Panorama Even In Presence Of Occlusions.
Panoramic mosaicing with videobrush
1997
As the eld of view of a picture is much smaller than our own visual eld of view, it is common to paste together several pictures to create a panoramic mosaic having a larger eld of view. While scissors and glue are the tools used in lm photography, more sophisticated methods were enabled with digital video.
Panoramic mosaicing optimization
2007
Motorized dome-type cameras, also called PTZ camera, allow the creation of panoramas. These panoramas represent the whole of the scene seen by the camera. In the case of a PTZ camera and with certain constraints, the scene seen by the camera can be considered as a sphere. The creation of a panorama consists in traversing a sphere in an exhaustive way. The acquired images are then projected on unspecified support which can be a cylinder, a cube or others. The projection of the rectangular images onto a sphere inevitably involves partial overlap between images. These overlaps lead to useless calculations. In order to limit the number of images we propose the calculation of an optimal trajectory for the camera according to intrinsic and extrinsic constraints.
