What Do We See? 3D world 2D image Figures © Stephen E. Palmer, 2002 This emphasizes that interpretation is inherently a difficult problem. It is ill-posed because there an infinite number of interpretations of a 3D scene. Figures © Stephen E. Palmer, 2002

What do we see? 3D world 2D image Painted backdrop It is impossible to know from pure visual processing if this scene is a backdrop or a real 3D scene. Painted backdrop Figures © Stephen E. Palmer, 2002

Brightness: Measurement vs. Perception Visual system tries to undo the measured brightness into the reflectance and illumination and estimate the reflectance that is inherent to the object. Do squares A and B have the same brightness?

Brightness: Measurement vs. Perception Squares A and B have the same measured brightness but a different perceived brightness!

Lengths: Measurement vs. Perception Müller-Lyer Illusion Our perception of geometric properties is affected by our interpretation. http://www.michaelbach.de/ot/sze_muelue/index.html

Which monster is larger? Shepard RN (1990) Mind Sights: Original Visual Illusions, Ambiguities, and other Anomalies, New York: WH Freeman and Company We can’t help but to integrate perspective cues into our interpretation of the image.

Find The Face In This “Coffee Beans” Image? We ourselves are susceptible to clutter as well. This is a problem where computer might do faster than human. http://www.michaelbach.de/ot/sze_muelue/index.html

Brain Fills In Occlusions

Segmentation and Grouping – Find The Dog This scene is really a collection of many random spots and dots but the brain can group them together to segment the dog from the background.

Is Face Processing Orientation Dependent?

Vision and Robotics What is in there?

What is context? Context is information relevant to the detection task but not directly due to the physical appearance of the object. Wolf and Bileschi, 2004 What do we mean by “context”? We can interpret the H or A based on context. Example from “Cognition in Action” Smyth Collins Morris Levy, 1994, LEA Publishers. In our case, we think of “the object” as a person’s face. Smyth et al., 1994

Engineering vs Science

Engineering vs Science Thomas Edison ($15,000,000,000) Nikola Tesla (~0)

Engineering vs Science Steve P. Jobs Samuel Hurst

Doctors vs Engineers

Different view! (Art+ Music+ Science)

The Key

[Computer] Engineering is all about fun!!!!!! So… [Computer] Engineering is all about fun!!!!!!

Creativity

An engineer father is like:

An engineer never gives up. Can you put four between five An engineer never gives up!!! Can you put four between five? Non-engineer says: NO Engineer: YES F(IV)E

You will learn physics

You will learn math

You understand the meaning of many things critically Why do we spell PITZA, pizza?

Value of last minute in Engineering

FAIL: Bad? Good?

An Apple

In Computer Engineering programme you will learn how to develop your CREATIVITY skills

Creativity S. Jobs: Creativity is just connecting things. When you ask creative people how they did it they feel a bit guilty because they didn’t really do it. It seemed obvious to them after a while. That’s because they are able to connect experiences they’ve had and synthesize new things.
