1. 定义：
   It aims to infer the location of an arbitrary target in a video sequence, given only its location in the first frame

2. 应用：
   traffic monitoring, robotics, autonomous vehicle tracking, medical diagnosis systems, activity recognition, and so on.

• monitoring of traffic flow and detection of traffic accidents
• ASIMO humanoid robot
• path-tracking
• tracking of ventricular wall and medical instruments control
• learning activity patterns and human activity recognition（比如说VR)

3. 挑战：

• Illumination Variation
• Background Clutters:the backgroundnear the targethas a similarcolor or textureas the target
• Low Resolution
• Scale Variation:the ratio ofbounding boxesof the first frameand the currentframe is out ofthe range
• Occlusion:the target is partially or fully occluded(被遮挡)
• Change the target position:During themovement, thetarget may berotated,deformed, and soon.
• Fast Motion:the motion of theground truth islarge

4. 方法：
   feature-based, segmentation-based, estimation-based, and learning-based methods
   

• generative methodsVS discriminative methods
  都需要求 P ( Y ∣ X ) P(Y\mid X) P(Y∣X)，即已知样本x，求其属于类别y的概率。不同的是generative methods需根据公式P(Y∣X)= \\frac{P(X∣Y)P(Y)}{P(X)} 来求，但 ' d i s c r i m i n a t i v e m e t h o d s ' 直接求 来求，但\`discriminative methods\`直接求 来求，但'discriminativemethods'直接求P(Y\\mid X)。(Note that deep learning is belong to discriminative methods)

5. 方法的评价：

• Robustness
• Adaptability
• Real-time processing of information
