PENGENALAN POLA DAN VISI KOMPUTER PENDAHULUAN

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 pictures and videos in order to achieve results similar to those as by men.

Example Finding People in images Problem 1: Given an image I Question: Does I contain an image of a person?

“Yes” Instances

“No” Instances

Every picture tells a story Goal of computer vision is to write computer programs that can interpret images

Can computers match human perception? Yes and no (but mostly no!) humans are much better at “hard” things computers can be better at “easy” things

Perception

Low level processing Low level operations Image enhancement, feature detection, region segmentation

Mid level processing Mid level operations 3D shape reconstruction, motion estimation

High level processing High level operations Recognition of people, places, events
