- Abstract:
-
To address the tracking failure problem caused by image blur in the tracking field, we propose a robust kernelized correlation filter (KCF) tracking algorithm combined with fuzzy feature detection. First, the scale invariant feature transform descriptor is combined with the local binary pattern algorithm to extract the feature points in the fuzzy image, and the circular neighborhood is used to describe the feature points and reduce the dimensions of the feature vector. Thus, the fuzzy feature detector is constructed. Next, the image definition threshold is set. If the definition of the current image is lower than the threshold, fuzzy feature detection is initiated to obtain the tracking target position by matching the feature vectors. Otherwise, the target position is predicted by the traditional KCF algorithm. The test results on the open data sets OTB-2013 and OTB-2015 show that the proposed algorithm can effectively track targets in fuzzy images with higher accuracy than other experimental algorithms
