How do you convert an image to gray scale?

What is GREY scaling in image?
Gray-scaling is the process of convertinga continuous-tone image to an image that a computer can manipulate. While gray scaling is an improvement over monochrome, it requires larger amounts of memory because each dot is represented by from 4 to 8 bits.

You just have to take the average of three colors. Since its an RGB image, so it means that you have add r with g with b and then divide it by 3 to get your desired grayscale image. Its done in this way.
What is the difference between an RGB image and a grey image?
RGB images vs grayscale images It is important to distinguish between RGB images and grayscale images. An RGB image has three color channels: Red channel, Green channel and Blue channel. However, a grayscale image has just one channel.
Why is gray scale important?
Grayscale is an important aspect of images, and it is the only portion that is not removed; otherwise, a pure black image would result no matter what color information there is. A digital image is composed of groups of three pixels with colors of red, green and blue (RGB), also called channels in digital imaging.
Why is grayscale used?
The main reason why grayscale representations are often used for extracting descriptors instead of operating on color images directly is that grayscale simplifies the algorithm and reduces computational requirements.
