Looking for algorithm for online CWT #96

Closed richardpl closed 1 year ago

richardpl commented 1 year ago

Is there reasonable algorithm for online CWT that is not using any input overlapping and is not introducing discontinuity at filter output boundaries? Using overlap surely works to some degree, but isn't this doing excessive calculations and then dropping/ignoring most of calculated values?

I already read this answer several time but I need more elaborated answer to be able to code usable and efficient solution.
