Target tracking based on incremental deep learning
As current tracking algorithms lead to target drift or target loss in the complex environment
a tracking algorithm based on the incremental deep learning was proposed under a double-resampling particle filter framework. To solve the problem of particle degradation and depletion
the double-resampling method was introduced to adapt to the particle size in particle filtering and a Stacked Denoising Autoencoder(SDAE) was pre-trained by the unsupervised feature learning to alleviate the lack of training samples in visual tracking. Then
the SDAE was applied to online tracking
so that the extracted feature sets could express the region image representations of the particles effectively. The incremental feature learning was introduced to the encoder of SDAE
the feature sets were optimized by adding new features and merging the similar features to adapt to appearance changes of the moving object. Moreover
a support vector machine was used to classify the features then to improve the classification accuracy of the particles and to obtain a higher tracking precision. According to the results of experiments on variant challenging image sequences in the complex environment
the
F
-measure and the overlapping ratio of the presented algorithm are 94%
74%
respectively and the average frame rate is 13 frame/s. Compared with the state-of-the-art tracking algorithms
the proposed method solves the problems of target drift and target loss efficiently and has better robust and higher accuracy
especially for the target in the occlusions
background clutter
illumination changes and appearance changes.
