Chapter 2

1. There are three image processing steps:
   
   1. Getting the necessary information to work with (for example, an image or video file, among others)
   2. Processing the image by applying image processing techniques
   3. Showing the results in the required way (for example, save the image to disk, show the image, and so forth)
2. The processing step can be broken down into three processing levels:
   
   1. Low-level processing
   2. Mid-level processing
   3. High-level processing

3. A grayscale image contains for every pixel of the image a value that is proportional to the brightness or gray levels of the image. This value is also called intensity or grayscale level. This value is ∈ [0, L-1], where L = 256 (for an 8-bit image).

On the other hand, black and white images contain for every pixel of the image a value that can only take two values. Usually, these values are 0 (black) and 255 (white...
