What is an image?

An image is a grid or matrix of intensity values, often represented by a 2D array of numbers. Each number in the array represents the brightness or color of a pixel at a specific location in the image.

What is a pixel?

A pixel is the smallest unit of an image, a single point on the image that can be assigned a color or brightness value.

Signup and view all the flashcards

What is pixel intensity?

In digital images, each pixel is assigned a numerical value representing its intensity. This value is usually an integer ranging from 0 to 255, where 0 represents black and 255 represents white. This range of numbers forms a grayscale scale for representing different colors.

How are images represented digitally?

An image can be visualized as a 2D array of pixels, where each pixel corresponds to a unique location on the image. Each location has an associated intensity value that determines the color or brightness at that point.

What is a 3D view of an image?

A 3D view of an image helps conceptualize the image as a layered structure, where each layer contains the intensity values for a specific color channel. For instance, in a color image, you'd have layers for red, green, and blue channels.
