We present a matched-filter based algorithm for transit detection and its
application to simulated COROT light curves. This algorithm stems from the work
by Bord\'e, Rouan & L\'eger (2003). We describe the different steps we intend
to take to discriminate between planets and stellar companions using the three
photometric bands provided by COROT. These steps include the search for
secondary transits, the search for ellipsoidal variability, and the study of
transit chromaticity. We also discuss the performance of this approach in the
context of blind tests organized inside the COROT exoplanet consortium.Comment: 6 pages, 4 figures, in Transiting Extrasolar Planets Workshop,
