Embodiment
[0118]The algorithm of this embodiment is implemented using Matlab R2018a and MatConvNet as development tools, and is debugged on an Intel(R)Core(TM)3.19GHz CPU and GeForce GTX Titan X GPU computer. Define the prediction search area as 100×100, and the output probability map as 50×50; set the number of particles in the three stages as N1= 3000, N2=400,N3=100. The experimental data of this embodiment is the OTB100 benchmark data set released in 2015 [Y.Wu,J.Lim,and M.-H.Yang.Object tracking benchmark[J].IEEE Transactions on Pattern Analysis and Machine Intelligence,2015,37 (9):1834–1848.], the benchmark library contains 100 videos, and these video sequences are annotated as 11 challenging attributes. The most intuitive and reliable evaluation method in this benchmark library is OPE (one-pass evaluation), which runs all videos from start to finish. In addition, there are two evaluation indicators: Precision (average center error, with 20 pixels as the threshold) and Success (the coinc...
