| Subject: [PATCH 157/299] [media] videodev2.h Add HSV formats |
| |
| 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. |
