This slide states that images are also essentially functions. Does this specifically refer tothe RGBA values of pixels of an image? Or is there some other representation of an image as a datatype that this slide is referring to?


How do we take something with so many different attributes (hue, saturation, intensity of color, etc.) and mathematically represent it? It will be interesting to see how we can manipulate these functions with some of the linear algebra concepts discussed later.


Are there any easy/intuitive ways to visualize vector spaces for functions (in the scope of this class at least)?
