WebRGB to HSV. This example illustrates how RGB to HSV (Hue, Saturation, Value) conversion [ 1] can be used to facilitate segmentation processes. Usually, objects in images have distinct colors (hues) and luminosities, so that these features can be used to separate different areas of the image. In the RGB representation the hue and the luminosity ... Web16 jun. 2024 · HSV, like HSL (or in OpenCV, HLS), is one of the cylindrical colorspaces. The name is somewhat descriptive of how their values are referenced. The hue is represented as degrees from 0 to 360 (in OpenCV, to fit into the an 8-bit unsigned integer format, they degrees are divided by two to get a number from 0 to 179; so 110 in OpenCV is 220 …
