Curve Flows (Java Applet)
4th Order Image Flow (Java Applet)

Comparsion of affine flow (AMSS) and our 4-th order flow:

Some basic curves:

a=4 a=1
a=1/9 a=1/16
a=1/49 a=1/100

Examples of AMSS (using MegaWave)

upleft: original image
upright: AMSS flow for 2 units of time
downleft: AMSS flow for 4 units of time
downright: AMSS flow for 8 units of time
(1 unit of time is about 20 steps)
