Fibered confocal microscopy allows in vivo and in situ imaging with cellular resolution. The potentiality of this imaging modality is extended in this work by using video mosaicing techniques. Two novelties are introduced. A robust estimator based on statistics for Riemannian manifolds is developed to find a globally consistent mapping of the input frames to a common coordinate system. A mosaic...

The general problem of mosaicing is to create a single seamless image by aligning a series of spatially overlapped images. The result is an image with a field of view greater than that of a single image. This paper proposes a framework for creating a panoramic view representing the background of a given image sequence, by discarding the foreground objects. Our system performs motion estimation ...

Video Mosaicing is the stitching of selected frames of a video by estimating the camera motion between the frames and thereby registering successive frames of the video to arrive at the mosaic. Different techniques have been proposed in the literature for video mosaicing. Despite of the large number of papers dealing with techniques to generate mosaic, only a few authors have investigated condi...

Recent works in sound mosaicing synthesis [1], [2] have proposed algorithms that permit instantaneous mixtures of several sources atoms, based on sparse signal representation techniques. We propose combining l1 regularization with linear dynamical smoothing as in the Kalman filter (also in [3], [4]) to promote desired transitions between atoms, while adapting the generic approach to the mixture...

This thesis investigates how audio analysis techniques and representations can be used to automate the sequencing of arbitrary sounds in order to provide a higher level and more expressive control over the creation of sample based music. This pursuit required the creation of a mosaicing algorithm prototyping language, which expedites the process of creating and testing different ways to interac...

Several image mosaicing algorithms claiming to advance the state of the art have been proposed so far. Though sometimes improvements can be recognised without quantitative evidences, the importance of a principled methodology to compare different algorithms is essential as this discipline evolves. Which is the best? What means the best? How to ascertain the supremacy? To answer such questions, ...

An algorithm for image registration and mosaicing on underwater sonar image sequences characterised by a high noise level, inhomogeneous illumination and low frame rate is presented. 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 can be...
