You may first bring your picture into the vision assistant, then try to tune the color using color image processing palette.

Extract the hue color plane from the color image. The ball should be a different hue value than the background. If you threshold in the orange range, you should get a highlight for the ball.
i already tried threshold but it did not work correctly (because of the shadows under the ball).i also used some kernel, filters, but it wasn't so helpfull.
could you show me an example which detects the orange ball in green background?
Extracting the hue color plane should give you a fairly high contrast image. All the orange pixels will be one hue value, and all the green pixels will be a different hue value. Brightness and saturation are ignored, so bright orange and dark orange should show up as the same hue. Same thing for green.
Can you post a sample image that we can work with? This makes it easier to understand the problems you are encountering, and we can provide more helpful suggestions.
I appreciate your cooporation, here i attach these two images which i want to detect the orange ball from. as you can see the shadow and the light affect on the detection and this is my problem.
please help me in detail, so that i can exactly detect the ball in the image.
