What is computer vision?

• A software for managing images

• Teaching computers to understand and interpret visual information

• A type of digital camera

• A new type of computer monitor

How does human vision work?

• By capturing images with the brain

• Through the sense of touch

• By taking in light with the eyes and processing it in the brain

• By using the nose to interpret visual information

Which of the following is a common source of visual input for computer vision systems?

• Audio recordings

• Taste tests

• Photographs and videos

• Temperature measurements

How does computer vision relate to the human visual system?

• It's unrelated to human vision

• It's focused on hearing instead of seeing

• It primarily processes taste-related information

• It aims to mimic human visual perception

When is computer vision especially advantageous?

• When handling complex visual tasks that are challenging to program explicitly

• When dealing with simple tasks that require minimal coding

• When you need to write explicit instructions for complex tasks

• When there is no need for visual data interpretation

What is the fundamental difference between traditional programming and computer vision?

• Traditional programming uses machine learning, while computer vision relies on explicit instructions

• Traditional programming doesn't involve coding, while computer vision requires extensive coding

• Traditional programming uses explicit instructions, while computer vision uses machine learning

• Traditional programming and computer vision are essentially the same

What is face detection in computer vision?

• Recognizing emotions displayed on a face

• Locating human faces in an image

• Identifying faces in a crowd

• Analyzing facial expressions

How does PictoBlox perform face detection?
