An image (from Latin: imago) is an artifact that depicts visual perception, such as a photograph or other two-dimensional picture, that resembles a subject—usually a physical object—and thus provides a depiction of it. In the context of signal processing, an image is a distributed amplitude of color(s).

What do you mean by digital image representation?

A digital image is an image composed of picture elements, also known as pixels, each with finite, discrete quantities of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with x, y on the x-axis and y-axis.

What is image in image processing?

What is an Image. An image is nothing more than a two dimensional signal. It is defined by the mathematical function f(x,y) where x and y are the two co-ordinates horizontally and vertically. The value of f(x,y) at any point is gives the pixel value at that point of an image.

What is difference between image and digital image?

An image is also a two-dimensional array specifically arranged in rows and columns. Digital Image is composed of picture elements, image elements, and pixels.

What is the description below a picture called?

Photo captions, also known as cutlines, are a few lines of text used to explain and elaborate on published photographs. Captions can also be generated by automatic image captioning software.
