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

After turning an image into grayscale, various methods can be applied to it. One such method is cropping or trimming an image. You reduce the number of pixels by keeping
a subsection of the original image from one pixel position to another pixel position.  

You are given a two-dimensional array of the grayscale image along with four indices, x1, x2, y1, and y2, representing the starting and ending rows and columns in the `crop` function below. Create an array `im` that takes a subset of the original array.

This lesson is an exercise on image preprocessing.
