Abstract. Fibered confocal microscopy allows in vivo and in situ imag-
ing 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 mosaicing framework using an
efficient scattered data fitting method is proposed in order to take into
account the non-rigid deformations and the irregular sampling implied
by in vivo fibered confocal microscopy. Results on 50 images of a live
