hello, i am trying to do a face detection based on skin colour and i was trying to make a uniform illumination for the images acquired through the webcam. How can I do this with help of HSV adjustments?

Illumination cannot be changed by software. You need things like lamps and diffusers. Simply converting to HSV or LAB color space and making the V or L channel (respectively) a uniform value does not have the same effect. Below is an image where I made the left half have the same Y value (like L or V). You can see the effect. If you would have had a non-uniform illumination, it would not flatten the image. You'd need to do background division for that.
