1.1 From image to image engineering
1.1.1 Image and digital image
• What is an image?
An image is a visual representation of pictures, animations, etc.. The difference between graphics and computer graphics is that computer graphics are from building mathematical models to generating graphics, and images usually refer to graphs generated from outside.

• Why do you need digital images?
Ordinary images contain enormous amounts of information and
require the use of computers to process images. Therefore, it is
graphics, consisting of finite rows and finite columns. Each basic unit
is called a pixel. The voxel of a three-dimensional image is also
called voxel. The two-dimensional digital image usually is a
rectangle, you can use a two-dimensional array of I (x, y) to said,
basic concept of image processing. The third, fourth chapter is space domain and frequency
domain transform The fifth, eighth chapter is image enhancement and
necessary to transform ordinary images into digital images that the
computer can process. Today's digital cameras can directly convert

visual images into digital images. A digital image, similar to raster
The objective world is a three-dimensional space, but the general image is two-dimensional. Two dimensional images inevitably lose part of the information in the process of reflecting the threedimensional world. Even recorded information can be distorted and even difficult to recognize objects. Therefore, it is necessary to recover and reconstruct information from images, and to analyze and extract mathematical models of images so that people can have a correct and profound understanding of what is recorded in the image. This process becomes the process of image processing.
