Non-regular optical flow for dynamic texture
Work in progress with Tel-Aviv Unversity (TAU)
Tomer Amiaz
Nahum Kiryati
Dynamic textures have strong
intrinsic dynamics
motion cannot be compensated by shift/rotation
intensity constancy
assumption not valid
standard (regular) optical flow not precise
Use
intensity conservation
assumption instead
non-regular optical flow with divergence term
intensity may diffuse
Dynamic texture detection
segmenting flow into regular and non-regular part
indicator function in level-set implementation
