Editing Chirp (section)

=== Chirplet transform ===
{{main article|Chirplet transform}}

Another kind of chirp is the projective chirp, of the form:
<math display="block">g = f\left[\frac{a \cdot x + b}{c \cdot x + 1}\right],</math>
having the three parameters ''a'' (scale), ''b'' (translation), and ''c'' (chirpiness). The projective chirp is ideally suited to [[image processing]], and forms the basis for the projective [[chirplet transform]].<ref name="Mann">Mann, Steve and Haykin, Simon;  The Chirplet Transform: A generalization of Gabor's Logon Transform; Vision Interface '91.[http://wearcam.org/chirplet/vi91scans/index.htm]</ref>
