The mosaicing technique has been employed in more and more application fields, from entertainment to scientific ones. In the latter case, often the final evaluation is still left to human beings, that assess visually the quality of the mosaic. Many times, a lack of objective measurements in microscopic mosaicing may prevent the mosaic from being used as a starting image for further analysis. In...

Image mosaicing constructs a wide field-of-view result from multiple source frames. In order to ensure a perceptually correct result, mosaicing typically requires either a planar or near-planar scene, parallax-free camera motion between source frames, or a dense sampling of the scene. When these conditions are not satisfied, various artifacts may result. A novel mosaicing approach is introduced...

Video mosaicing is commonly used to increase the e ective visual eld of view. Existing mosaicingmethods are based on image alignment, and are e ective only in very limited cases. To overcome most restrictions, mosaicing is presented in this paper as a process of collecting strips. Strips which are perpendicular to the optical ow are cut out of the images, and are warped so that within each stri...

Interest towards image mosaicing has existed since the dawn of photography. Many automatic digital mosaicing methods have been developed, but unfortunately their evaluation has been only qualitative. Lack of generally approved measures and standard test data sets impedes comparison of the works by different research groups. For scientific evaluation, mosaic quality should be quantitatively meas...

This paper presents improved techniques and applications in mosaicing of underwater video images. The applications are of use to many marine scientists. High resolution seabed maps are created. The improvements in the processing relate to removal of interframe variability and lighting, speed up of the mosaicing process and improved accuracy in the estimation of the transformation parameters. Re...

The modeling of facial appearance has many applications. This paper proposes an approach to generating a statistical face model based on video mosaicing. Unlike traditional video mosaicing, we use the geometry of a face to improve the mosaicing result. Given a face sequence, each frame is unwrapped onto certain portion of the surface of a sphere, as determined by spherical projection and the mi...

Image mosaicing overcomes the limitations of a camera’s limited field of view by aligning and pasting suitably transformed frames in a sequence of overlapping images. This paper deals with multispectral mosaicing for enhancement of spectral information – information from the thermal infra-red (IR, hereafter) band and visible band images is directly fused at the pixel level. All subsequent opera...
