| 英文摘要 |
| An improved LRECT tracking algorithm based on ECO (efficient convolution operators for tracking) is
proposed in this paper. Firstly, in order to enhance the extracted features for object recognition, a 32-convolution layers
LTRNet (linear two-step residual network) composed of LT (linear-two step) residual structures is designed as the features
extraction module of LRECT, and its shallow and deep features information are fused. Secondly, the projection matrix is
used to compress the high-dimensional features extracted by LTRNet, and the compressed features are interpolated, then
they are convoluted with the current filter to get the object location in the Fourier domain. Finally, filter and projection
matrix are updated by Gauss-Newton and conjugate gradient methods which are applied to solve the optimization problem,
and the optimization goal is the sum of response errors and penalties. The results of experiments on the OTB2015 dataset
show that the proposed algorithm can achieve robust tracking with a higher accuracy. |
