DEF	The target is deformable during tracking
OCC	The target is partly or fully occluded during tracking
OV	The target partly or fully leaves the image
SC	The ratio of the target size is out of the range［0.5，2］
FM	The target moves more than 20 pixels
MB	The target is blurry due to the target or camera motion
LR	The target size is lower than 800 pixels
ARV	The target aspect ratio is out of the range［0.5，2］
