Analysis of traditional tracking in the UAV123 database without scale estimation (showing some videos with typical tracking problems).

Video name	Tracking failure location	Failure reason description	Video name	Tracking failure location	Failure reason description
Car1	1/3	Scale+background change	Person12	3/5	Shelter
Car3	4/5	Background accumulation	Person14	1/10	Shelter
Car6	1/3	Out of sight	Person16	1/5	Shelter
Car9	2/5	Occlusion+scale change	Person21	1/100	Small target
Car11	1/100	Small target	Person1_s	1/3	Similar target
Car15	1/100	Small target	Truck1	1/2	Illumination change and deformation
