Solving segmentation issues is not a simple and a straight 
forward image processing solution and there is no fixed 
way of dealing with such problems.
What I might suggest you, is to go for LabColor 
segmentation procedures, very well explained in the Image 
Processing ToolBox Demos and probably try to segment the 
white ball. Or try using Hough Transformation to detect 
circular objects and then segment out the circular golf 
ball
All the best
