COMPUTER VISION• Introduction• System of Computer Vision• Applications• Example
WHAT IS COMPUTER VISION?• Computer vision is a field that includes methods for acquiring, processing, analyzing, and understanding images• Known as Image analysis, Scene Analysis, Image Understanding• duplicate the abilities of human vision by electronically perceiving and understanding an image• Theory for building artificial systems that obtain information from images.• Image data can take many forms, such as a video sequence, depth images, views from multiple cameras, medical scanner, satellite sensors etc.
COMPUTER VISION VS HUMAN VISION What we see What a computer sees
COMPUTER VISION VS HUMAN VISION…• Vision is an amazing feat of natural intelligence• More human brain devoted to vision than anything else• There are about 30,000 visual categories. • Learn 4.5 categories per day 18 years • At age 6, child can learn roughly all 30,000 (13.5day)• Machines Cant Replicate Human Image Recognition, Yet. they do not possess our ability to recognize distorted images
WHY IS COMPUTER VISION DIFFICULT?• It is a many-to-one mapping• It is computationally intensive• We do not understand the recognition problem
