Histogram Equalization before extracting color on a real time video

Is it a good practice to use the histogram equalization on the colored image before extracting its color during a real-time video stream? I have seen some people using but I have not seen any tutorial doing that. How does it behave with luminosity changes? Are there certain cases that it might help?

If you doing histogram equalization you need to first color convert it to a color space with a luminance channel, like Lab, HSV or YCrCb and then only equalize the luminance. If you try equalizing the RGB channels you will get weird color shifts.
