Data Science and Machine Learning (Theory and Projects) A to Z - Image Processing: Converting an Image to Grayscale in P

The video tutorial explains how to manipulate image channels and convert images to grayscale. It begins with an overview of image channels and their manipulation, followed by a demonstration of converting an image to grayscale using uniform averaging. The tutorial then introduces a more realistic method using weighted averages for each color channel. Finally, it compares the results of manual conversion with those from the OpenCV library, highlighting the limitations of reversing grayscale images back to color.

What are the weights assigned to the red, green, and blue channels in a more realistic grayscale conversion?
