Introduction to CV solutions
The goal of CV solutions is to gain insights, meaning, and understanding from an image; that is, what information is the image telling me?
Image processing
CV’s capabilities are built upon the concept of interpretation, understanding, and manipulation of an image through its pixel values; computers see an array of numeric pixel values when they look at an image.
This computer processing of images is illustrated in Figure 6.1, which shows how a slice of pepperoni pizza (my personal favorite; no pineapple allowed) would appear to a computer:
Figure 6.1 – How an image appears to a computer
Images are seen as pixel arrays, the array in Figure 6.1 is made up of 7 rows and 5 columns; the image resolution is therefore expressed as 7 x 5. Each pixel in the array for a color image is given a numeric pixel value that represents the RGB channels (layers); for grayscale images, the pixel values would be represented...
