Study on the Automatic Basketball Shooting System Based on the Background Subtraction Method

Table 3

Three detection algorithm methods’ comparison between each other.

	Optimal flow	Interframe subtraction	Background subtraction
Detection results	Whole region	Target contour	Whole region
Algorithm complexity	Big	Small	Decided by the background model
Applicable scene	Camera position can change	Camera position must be fixed	Camera position must be fixed
Robustness	Poor	Good	Little good
Advantages	Extent applicable field	Easy to compute	Complete segmentation and low complexity
Disadvantages	Slow computing speed	Incomplete detection target	Need to update the background model
