The multiscale edges of a signal are the sharp variation points measured at different scales. This thesis studies a model of multiscale edge representation based on the local maxima wavelet… Expand

The authors devise a class of fast wavelet based algorithms for linear hyperbolic and parabolic equations whose coefficients are time independent.Expand

The optimal reconstruction is an advanced decoding technique for the transform-quantization image coding schemes such as JPEG that does not suffer from Gibbs artifact.Expand

Summary form only given, as follows. A multiresolution edge detection can be performed with a wavelet transform. Indeed, for some particular wavelets, the wavelet transform of an image provides the… Expand
