Sonification der Gedanken

Klang und Farbe stehen in unmittelbarer Beziehung, das erkennt man schon an den Worten „Farbton“ und „Klangfarbe“.

Durch Open CV ändern Colorspaces

Sonification

There are more than 150 color-space conversion methods available in OpenCV. But we will look into only two which are most widely used ones, BGR ↔ Gray and BGR ↔ HSV.

For color conversion, we use the function cv.cvtColor(input_image, flag) where flag determines the type of conversion.

For BGR → Gray conversion we use the flags cv.COLOR_BGR2GRAY. Similarly for BGR → HSV, we use the flag cv.COLOR_BGR2HSV. To get other flags, just run following commands in your Python terminal :

For HSV, Hue range is [0,179], Saturation range is [0,255] and Value range is [0,255]. Different software use different scales. So if you are comparing OpenCV values with them, you need to normalize these ranges.
