Identification of morphological features discriminating between limb buds and face condensations. (a) Brightfield stereoscopic images of condensations are (b) converted to grayscale, (c) binarized and (d) watershed segmented to identify individual objects. (e) Weighting coefficients for morphological descriptors of individual condensation arising from linear discriminant analysis between face and limb condensations. Higher absolute values indicate most significant descriptors
