We propose an automatic image mosaicing method which can construct a panoramic image from a collection of digital still images. Our method is fast and robust enough to process a nonplanar scene with unrestricted camera motion. The method includes the following two techniques. First, we use a multiresolution patch-based optical flow estimation for making feature correspondences to obtain a homog...

It is a common phenomenon in day to day life; where in some of the document gets damaged. Out of several reasons, the main reason for documents getting damaged is shredding by hands. Recovery of such documents is essential. Manual recovery of such damaged document is tedious and time consuming task. In this paper, we are describing an algorithm which recovers the original document from such shr...

In real-time monitoring process, resolution must be set against field vision. There are two problems in the real-time monitoring procedures, which are: the field vision is too small to capture the target completely and a larger field vision with low resolution . In order to solve these problems, a new type of real-time panoramic monitoring systems becomes necessary. In this paper, we proposed a...

High-resolution image mosaics construction is one of the significant topics of research in the fields of computer vision, image processing, and computer graphics. Video mosaics contain enormous valuable information but when analyzing, searching or browsing a video, redundancy between frames creates problem. Therefore it is more suitable to bring together all the frames of a shot into one single...

We discuss a fingerprint mosaicing scheme to construct a composite fingerprint image using multiple impressions of the same finger. The composite image is expected to contain more information (e.g., minutiae) compared to the individual impressions thereby improving matching accuracy. The novelty of the proposed algorithm lies in its ability to account for the elastic deformation present in cons...

This paper presents an algorithm for image registration and mosaicing on underwater sonar image sequences characterized by a high noise level, inhomogeneous illumination and low frame rate. Imaging geometry of acoustic cameras is significantly different from that of pinhole cameras. For a planar surface viewed through a pinhole camera undergoing translational and rotational motion, registration...

In this paper, a novel quantitative assessment approach for image mosaicing algorithms is proposed by evaluating the quality of an output mosaic image and comparing with the input images. Five evaluation indices—entropy, clarity, registration error, peak signal-to-noise ratio, and structural similarity—are calculated and combined with the analytic hierarchy process for comprehensive assessment....

Practically all image rendering methods today use the perspective projection, or try to approximate it. We develop a new image-based rendering approach which is based on a new projection model – the Crossed-Slits X-Slits projection. The model is obtained by relaxing the requirement that all projection rays intersect at a single point (the focal-point). Instead, projection rays are required by d...
