Machine Learning-Based Multitarget Tracking of Motion in Sports Video

Table 1

Comparison of the analysis of three tracking methods.

Tracking method	Advantage	Disadvantage
Point tracking	Suitable for translational movements with small targets	When the target shape is obscured, point tracking
Nuclear tracking	When the target contour is a geometric rigid body, the effect is better	Inability to effectively track a small number of feature points’ illumination and target morphology changes have high sensitivity
Silhouette tracking	It has a significant effect on tracking nonrigid bodies with complex shapes	High requirements for target model establishment
