10 Questions
Explain digital image processing and its advantages over analog image processing.
Digital image processing is the use of a digital computer to process digital images through an algorithm. It allows a wider range of algorithms to be applied to the input data and can avoid problems such as noise and distortion during processing. This contrasts with analog image processing, which is limited in the types of algorithms that can be applied and is more prone to noise and distortion.
What factors have mainly affected the generation and development of digital image processing?
The development of computers, the development of mathematics (especially discrete mathematics theory), and the increasing demand for applications in various fields such as environment, agriculture, military, industry, and medical science have mainly affected the generation and development of digital image processing.
In what form can digital image processing be modeled due to images being defined over two dimensions?
Digital image processing may be modeled in the form of multidimensional systems due to images being defined over two dimensions.
What is the history of digital image processing influenced by?
The history of digital image processing is influenced by the development of computers, the development of mathematics (especially discrete mathematics theory), and the increasing demand for applications in various fields such as environment, agriculture, military, industry, and medical science.
What is digital image processing a subcategory or field of?
Digital image processing is a subcategory or field of digital signal processing.
What is the primary function of a communications satellite?
Relaying and amplifying radio telecommunication signals
At what altitude are many communications satellites in geostationary orbit?
22,300 miles (35,900 km)
Why are ground station satellite dish antennas aimed permanently at satellites in geostationary orbit?
So that the satellite appears stationary in the sky
Where are satellite constellations typically formed?
Low Earth orbit
Why do telecommunications links via radio waves used by communications satellites travel by line of sight?
Radio waves are obstructed by the curve of the Earth
