To achieve the complete three-dimensional (3-D) data retrieval of the shape of dentition, dental casts were measured from four directions; occlusal, right, left, and labial sides using a line laser scanner. Reconstruction of the entire shape, including undercuts and tooth crowding area, was attempted by applying a perceptual grouping algorithm, which is one(More)
This paper considers a wavelet-based approach to the blind separation of signals (BSS) including reflections such as sound. The BSS for the instantateous mixture case is achieved by maximizing the mutual information between input and output signals or by zeroing the cross-correlations of separated signals. For making these methods applicable to the(More)
