发帖数: 650 | 1 Guassian filter can be generated in matlab by one function. I forgot its name.
try guassian or something like it.
In fact, any vector can be a filter such as :[.1,.3,.9,.3,.1] and you have to
normalize it, of course. for low pass filters, big elements in the middle,
small ones on both sides. for high pass, reverse.
tell more why your @ point is the answer. there must be a prior knowledge to
find the answer. you can't just give some data and segment it, i think
