  annote={We are interested in photometric stereo setups in which the
illumination conditions used to acquire input images are completely
unknown except that they are provided by a single point illuminant at
infinity.  So far, such {\em uncalibrated} photometric stereo setup
has been understood for Lambertian surfaces only.  We analyse the 
case in which the reflectance function is a general one.},
