CNN’s consider images as 3D objects. A CNN processes RGB images in a way that R, G, and
B are ingested separately like they are stacked vertically together. This means that standard color
images are perceived by CNN as a rectangle; its height and width are determined via its pixels
and dimensions while the depth is considered as three-layer deep because of the RGB encoding.
When images move in CNN, they have to be described by the volumes of their input and output
with a mathematical representation of their multidimensionality through the 30×30×3 format.
Before working with CNN, it is mandatory to gain a rudimentary knowledge of linear
