WHAT IS COMPUTER VISION Automatic understanding of images and video

Computing properties of the 3D world from visual data (measurement)

Algorithms and representations to allow a machine to recognize objects, people, scenes, and activities. (perception and interpretation)

Algorithms to mine, search, and interact with visual data (search and organization)

HUMAN VISION Vision is the process of discovering what is

present in the world and where it is by looking .

COMPUTER VISION Computer vision is the study of analysis

of picture and video in order to achieve similar to those as by people.

COMPUTER VISION VS. HUMAN VISION

WHAT DOES RECOGNITION INVOLVE?

Detection: are there people?

Activity: What are they doing?

Object categorization

mountain

buildingtree

banner

vendorpeople

street lamp

Attribute recognition

flat

graymade of fabric

crowded

WHY RECOGNITION? Recognition a fundamental part of

perception e.g., robots, autonomous agents

Organize and give access to visual content Connect to information Detect trends and themes

APPLICATION

USING COMPUTER VISION: FACIAL EXPRESSIONS

Here are pictures of people and their expressions. As you can see, below the faces, the camera can sense where the main features change in the face.

COMPUTER VISION : SPEAKING WITH EYES The computer senses your eyes and notices the

eye movements. When someone blinks the computer would click something.

Looking into the side, or raising eyebrows are some ways to communicate with your eyes in the computer.

There’s also the eye gaze detection that detects where you are trying to move to.
