This paper reviews the concept of image mosaicking and presents a comparison between two of the most common image mosaicing techniques. The first technique is based on normalized cross correlation (NCC) for registering overlapping 2D images of a 3D scene. The second is based on mutual information (MI). The experimental results demonstrate that the two techniques have a similar performance in mo...

Due to their very small contact areas and low cost, swipe fingerprint sensors provide the very convenient and reliable fingerprint security solutions and are being increasingly used for mobile phones, PDAs, portable computers and security applications. In this paper, the minimum mean absolute error as the registration criterion is used to find an integer translation shift while the extension of...

Image mosaic is an important research content in digital image processing, and could be used to solve the problem of observing large objects with narrow view, such as 360 degree panorama stitching. Microscopic observation of liver biopsy is a commonly used method in diagnosing liver diseases, which are always rely on the whole liver slice. Therefore, the liver pathological microscopic image mos...

We present a complete step-by-step approach to calibration of ultra wide angle fish-eye lenses with the angle of view larger than 180◦. Such a large field of view is necessary for some applications such as the 360 x 360 mosaicing. Recently, a Nikon FC-E8 fish eye lens converter with the field of view equal 183◦ become available. In this paper, we propose its model, suggest a calibration procedu...

Text is no longer confined to scanned pages and often appears in camera-based images originating from text on real world objects. Unlike the images from conventional flatbed scanners, which have a controlled acquisition environment, camera-based images pose new challenges such as uneven illumination, blur, poor resolution, perspective distortion and 3D deformations that can severely affect the ...
