Why is HSV preferred?
The reason we use HSV colorspace for color detection/thresholding over RGB/BGR is that HSV is more robust towards external lighting changes. This means that in cases of minor changes in external lighting (such as pale shadows,etc. ) Hue values vary relatively lesser than RGB values.
What is HSV color space used for?
HSV Color Scale: The HSV (which stands for Hue Saturation Value) scale provides a numerical readout of your image that corresponds to the color names contained therein. Hue is measured in degrees from 0 to 360. For instance, cyan falls between 181–240 degrees, and magenta falls between 301–360 degrees.
Which of the following are advantages of the HSV Colour space with respect to the RGB Colour space?
The simple answer is that unlike RGB, HSV separates luma, or the image intensity, from chroma or the color information.
Why do we use HSV in Opencv?
The HSV or Hue, Saturation, and value of a given object provide better performance when compared to RGB or Red, Blue, and Green color space and hence it is used widely in the area of computer vision.
