What are the basic concepts in digital image processing?
The purpose of this chapter is to introduce you to a number of basic concepts in digital image processing that are used throughout the book. Section 2.1 summarizes the mechanics of the human visual system, including image for- mation in the eye and its capabilities for brightness adaptation and discrimi- nation.
Where is digital image processing printed?
Printed in the United States of America. The purpose of this chapter is to introduce you to a number of basic concepts in digital image processing that are used throughout the book.
What is a geometric transformation in digital image processing?
In terms of digital image processing, a geometric transformation consists of two basic operations: (1) a spatial transformation of coordinates and (2) intensity interpolation that assigns intensity values to the spatially transformed pixels. The transformation of coordinates may be expressed as
What determines the quality of a digital image after sampling and quantization?
Figure 2.17(b) shows the image after sampling and quantization.Clearly,the quality of a digital image is determined to a large de- gree by the number of samples and discrete intensity levels used in sampling and quantization. However, as we show in Section 2.4.3, image content is also an important consideration in choosing these parameters.
