B-spline based multiscale signal derivative filtering
We first generalize the multiscale filter proposed by Li and Ma[1] and then we use the method and B-spline as its kernel to construct multiscale derivative filters, we show that the filter can be recursively i...

Derivatives in scale space
Various derivatives (1st to 4th order) describe different signal characters in scale space: the first derivative represents signal variation which can be used for coding; the second derivative characterizes th...
