Image mosaicing involves geometric alignment among video frames and image compositing or blending. For dynamic mosaicing, image mosaics are constructed dynamically along with incoming video frames. Consequently, dynamic mosaicing demands efficient operations for both alignment and blending in order to achieve real-time performance. In this paper, we focus on efficient image blending methods tha...

This thesis describes a novel video mosaicing method which is capable of generating a geometric distortion-free mosaic image. Video mosaicing, which stitches partial images of a target into a larger image called a mosaic image, has been used to obtain high resolution images of documents. Generally, mosaic images are prone to two types of geometric distortions: perspective distortion which appea...

With the advent of cheap, but relatively low-resolution, video sensors, the importance of automatically mosaicing many small video images to one large image has increased. This is due mainly to the many useful applications that may be based on such technology, such as hand-held mobile scanning, multi-resolution imaging, panoramic spreads and video compression. The process of creating a mosaiced...

If it is impossible to capture all the image in one scan with the available equipment, a montage can be made from separately scanned pieces. We describe an automatic mosaicing process for document images. The image shifts are found by a correlation technique, using an image pyramid and sequential similarity to reduce computation time. Image placement and overlap is used to reject incorrect solu...

Image registration is the process of overlaying images (two or more) of the same scene taken at different times, from different viewpoints, and/or by different sensors. The registration geometrically aligns two images (the reference and sensed images). Many applications require a panoramic image of the object but due to limitation of apparatus, only a single image of the object in large scale c...

While a large number of virtual reality applications, such as fluid flow analysis and molecular modeling, deal with simulated data, many newer applications attempt to recreate true reality as convincingly as possible. Building detailed models for such applications, which we call tele-reality, is a major bottleneck holding back their deployment. In this paper, we present techniques for automatic...

Recent US systems allow the real-time acquisition of volume data, either by freehand 3D techniques or novel transducer hardware. However, the acquisition of large volumes is limited by the field of view of the US transducer and anatomical scanning windows into the patient. Mosaicing of several 3D US scans has been proposed to generate large US volumes. Still, US imaging specific characteristics...

Common surveillance system is usually limited by the scope of observation, which may increase the probability of missing or misjudging suspicious targets. A wide-field monitoring system based on efficient image mosaicing algorithm is proposed in this paper. It can monitor a wide field for both short and long distance in real time and highlight the detected moving objects simultaneously. The ima...

In this article, we present some development results of a system that performs mosaicing (or mosaicking) of panoramic faces. Our objective is to study the feasibility of panoramic face construction in real-time. To do so, we built a simple acquisition system composed of 5 standard cameras which, together, can take simultaneously 5 views of a face at different angles. Then, we chose an easily ha...

Considering the mismatch and the high computational complexity of video mosaicing, a fast stitching method based on the normalized covariance is proposed. Firstly, the image corner features are extracted using the SURF algorithm and the corresponding matching points are found using the nearest neighbor method. The least square method is used to filter the matching points and accurately match th...
