How are images used in computer science?
Images are stored inside a computer's memory in binary form, as combination of zeros and ones.
Every pixel from an image is converted into a binary value, and this digital data is what the computer reads and processes..
How computers represent images?
An image is made of many pixels, each of them with a particular color.
Modern computers can show up to 16.7 millions of different colors.
It is impossible to store each one of these colors personnally, they are instead represented as a combination of three primary colors: red, green and blue (RGB color model)..
How do computers process images?
Image processing requires fixed sequences of operations that are performed at each pixel of an image.
The image processor performs the first sequence of operations on the image, pixel by pixel.
Once this is fully done, it will begin to perform the second operation, and so on..
What are images in computer science?
A computer image is a picture composed of an array of elements called pixels.
The illustrations in the rest of this book contain printed examples of images.
When printed, each pixel is either a small patch of ink or a small area of blank paper..
What does computer science look like?
Computer science combines the principles of engineering, mathematics and science to study and develop computers, networks, hardware, software, databases and much more.
Because of that, there is a wide range of potential careers within the field, from software engineering to computer programming or system analysis..
What is a computer image made of?
Computer based images are comprised of thousands of tiny dots of color called pixels.
These are the small dots you see if you put your face too close to your television or computer screen.
Each digital image is comprised of thousands or millions of individual pixels, each with its own color..
Why does a computer represent an image?
Everything you see on computer screens, whether it is photographs, videos, websites, even text, is an image that a digital device has been programmed to display.
Because computers store data as digits, computer images are ultimately represented inside a computer using just 0's and 1's..
- Since computers see images as millions of individual pixels each with colour and alpha values it's difficult for a computer to determine if there are “things” in the image, so we remove data.
Data is generally colours, and areas of the image that we know don't contain any points of interest to us.
