Create a computer vision system using decision tree algorithms to solve a real-world problem : What is an image and how

The video tutorial covers the representation of images in digital formats, starting with an introduction to the importance of digital image representation in machine learning. It explains how humans perceive colors through light wavelengths and the visible spectrum. The tutorial then delves into grayscale image representation, detailing how pixels are stored in decimal and binary formats. Finally, it explores colored image representation using the RGB model, explaining how different colors are formed by mixing red, green, and blue channels.

What is the range of wavelengths that humans can see, known as the visible spectrum?

• 400 to 700 nanometers

• 200 to 500 nanometers

• 300 to 600 nanometers

• 500 to 800 nanometers

In a grayscale image, what does a pixel value of 0 represent?

• White

• Gray

• Black

• Red

How is the number 255 represented in binary format?

• 11111111
