theory

Using RATP open data for live visualisation (in progress)

After diving into color perception in the previous blog post, I got interested into understanding more another sensor that mammals have: hearing. Light is a electromagnetic wave, where sound is a mechanical one, but the comparison is relevant because both sound and light signals can be described as a spectrum of wavelenght.

Recently, I read an article claiming that the color pink doesn’t exist, and is only an illusion from our brain. Because I struggle to accept this idea, this is the motivation into diving in the understanding of the human perception of colors.

Because my thesis aims at hiding information in digital images, let’s first dive into the origins of colour theory and then digital images.
