Explore how computer systems store, manipulate, and convert various data types like text, images, and videos through integrated software and hardware. Gain insights into accessible data representation.

Computer systems do not understand human instructions, nor can they perceive real-life data in its raw form. Therefore, computer systems require a way to store and represent information in an accessible way. They use software and hardware components combined to help retrieve information, store it, manipulate it, and convert it back to a human-accessible format. If you want to learn how computer systems perform complex tasks such as storing and manipulating textual data, videos, music, images of your cat, and much more, this course is meant for you.

Information Representation in Computer Systems

There are various kinds of methods that can be used to convert a colored image into a grayscale image. A simple method that we can use requires us to take the average of the three channels at each pixel position. That reduces the dimensionality of the image, thereby reducing the number of bits that we require to store it. Figure 1 shows a colored image. Your job is to convert it into a grayscale image by averaging the three channels in each pixel.

This lesson is an exercise on image preprocessing.
