Animal camouflage

Hello everyone,

Believe it or not, we've gotten interested in animal camouflage. Come to our next meeting to find out why. Here are the papers we'll focus on:

R. Hanlon. 2007. Cephalopod dynamic camouflage. Current Biology, 17, 11, R400-R404.

Cuthill IC, Stevens M, Sheppard J, Maddocks T, Párraga CA, Troscianko TS. 2006. Disruptive coloration and background pattern matching. Nature 434(7029), 72-4.

Martin Stevens, Innes C. Cuthill. 2006. Disruptive coloration, crypsis and edge detection in early visual processing. Proc. Royal Society B, 273, 1598, 2141-2147.

...and here is some more detail we likely won't get to this time around:

Chuan-Chin Chiao and Roger T. Hanlon. 2001. Cuttlefish camouflage: visual perception of size, contrast and number of white squares on artificial checkerboard substrata initiates disruptive coloration. J. Experimental Biology 204, 2119-2125.

Kelman EJ, Baddeley RJ, Shohet AJ, Osorio D. 2007. Perception of visual texture and the expression of disruptive camouflage by the cuttlefish, Sepia officinalis. Proc Biol Sci. 274(1616):1369-75.

Lydia M. Mäthger, Alexandra Barbosa, Simon Miner and Roger T. Hanlon. 2006. Color blindness and contrast perception in cuttlefish (Sepia officinalis) determined by a visual sensorimotor assay. Vision Research, 46, 11, 1746-1753.

A paper on effective icons

Hi folks,

Eric Price and I have just begun working with Vidya Setlur at Nokia Research on effective use of icons on phones. This goes along with our lab's theme of creating visual meaning. Here's one paper I've been reading lately about icons; let's all talk about it:

Susan Wiedenbeck, 1999. The use of icons and labels in an end user application program: an empirical study of learning and retention. Behaviour and Information Technology, 18, 2, 68-82.

Parallel Controllable Texture Synthesis


Next Thursday we'll read a paper that Alex and I have been studying lately: Parallel Controllable Texture Synthesis, by Lefebvre and Hoppe.

Some possibilities for the near future:

Elder's paper on contour matching
Morgan's paper on hyperacuity
Hachisuka on Parthenon rendering

Back in Action!

Hi folks,

We're back in action, meeting Thursdays at 4.

In each meeting, we'll talk what our lab is up to, and then either go over a recent conference or journal, or talk about one or more papers we're considering in our research.

We'll consider one such event or journal at the first meeting of each month, starting in March.
Next week, let's go over James Elder's paper Are Edges Incomplete? one more time together (I expect we'll spend more time on it outside of the meeting).
