I have one question! What is the reason that My HoughCircles function sometimes can detect the ball sometimes not?

there is just one ball in the scene, without any movement... sometimes HoughCircles can detect it sometimes not!

any idea will be appreciated..

Do you use real images or self drawn ones? If you draw your pictures, you should filter them with a lowpass filter to get proper results from HoughCircles.
