  • Xyz. Xyz is an additive color space based on how the eye intereprets stimulus from light. Unlike other additive rgb like Rgb, Xyz is a purely mathmatical space and the primary components are "imaginary", meaning you can't create the represented color in the physical by shining any sort of lights representing x, y, and z.
  • Opencv rgb to hsv python. Changing Colorspaces, HSV. For color conversion, we use the function cv2.cvtColor(input_image, flag) where flag In HSV, it is more easier to represent a color than RGB color-space.
  • HSV color space is more often used in machine vision owing to its superior performance compared to RGB color space in varying illumination levels. HSV color space of OpenCV is a bit complicated than other software programmes like Gimp, Photoshop etc.So I have written a small python script to grab...

Lets back to basics..splitting RGB channels in OpenCV can be done using split function. Note that the function returns RGB in reverse order (BGR). Here is the code. Additionally same code can be used to get HSV and YCrCb as well, as you can see in commented section. cheers.
Hey guys, been reading OpenCV for python and thought of posting a tutorial on Programming a Grayscale Image Convertor. I encourage you to google them , there are lots and lots of examples and code snippets.

RGB stands for “Red, Green, Blue”, and consists of a tridimensional spectrum of colors that is considered additive, as colors are created from the addition of each of the three dimensions [7]. Illustration 1 depicts the RGB scale in a graphical manner. HSV (Hue, Saturation, Value) is a cylindrical projection of a RGB color cube [7], which ...
