Subject: [PATCH v2 1/6] [media] videodev2.h Add HSV formats
Date: Fri, 15 Jul 2016 18:13:14 +0200 [thread overview]
Message-ID: <1468599199-5902-2-git-send-email-ricardo.ribalda@gmail.com> (raw)
In-Reply-To: <1468599199-5902-1-git-send-email-ricardo.ribalda@gmail.com>
These formats store the color information of the image
in a geometrical representation. The colors are mapped into a
cylinder, where the angle is the HUE, the height is the VALUE
and the distance to the center is the SATURATION. This is a very
useful format for image segmentation algorithms.
