We cloned the chick homolog of Xenopus and mouse Frzb-1, a secreted Wnt antagonist and performed in situ hybridisations to determine the pattern of cFrzb-1 expression in the developing chick embryo. At early stages, cFrzb-1 transcripts are located exclusively in the ectodermal layer corresponding to the neural plate. The labelling continues in the neural tube, but is always excluded from the ̄o...

We present a general algorithm for plane-based calibration that can deal with arbitrary numbers of views and calibration planes. The algorithm can simultaneously calibrate different views from a camera with variable intrinsic parameters and it is easy to incorporate known values of intrinsic parameters. For some minimal cases, we describe all singularities, naming the parameters that can not be...

If no one asks me, I know; if I wish to explain it to one that asketh, I know not. 1 The present document is about time, in at least two respects. Firstly, it gives a description of my scientific work over the time since the completion of my PhD thesis [85]. Secondly, this te...
