Intro to Computer Vision
With OpenCV & Python
Defining an Image
An image is a 2D perception of light.
Humans tend to perceive light as a continuous wave.
Visible light, tends to have colors based on their wavelength.
All colors can be obtained using 3 primary colors, Namely RGB.
How Computers Perceive Images (DIP)
An image is a 2D, array with discrete
Intensities of light at a certain moment.
All colors are combination of Red, Green and
Blue, called RGB Channels.
Simply Put, colored images are 2D arrays
with one layer for each color.
Example
[[1,0,1,0],
