Hi all,

Wondering whats the implication of increasing the filter length of a
2D FIR filter? wat are the applications of a long filter length (eg.
N>40) in image processing?

Thanks alot

In general, longer filter lengths are used to achieve specific parameters,
such as a sharper cutoff (smaller transition bandwidth) and/or better
stop-band attenuation.
