Dynamic Visual Attention: Searching for coding length increments
Xiaodi Hou and Liqing Zhang (W-77)

The Incremental Coding Length (ICL)

Feature can be sampled in various ways
t t-1 t-2 t-3

H(p)
Sampling a new feature changes the whole distribution

P(t) P Multiimage sampling

Feature distribution

H(p)

Single image sampling

P(t1)
What are we looking for? Common features reduce entropy non-salient Rare features gain entropy SALIENT!

P(t2)

P(t3)

Foveated sampling: Attention shift on one image Inhbition of return
