[0040] The present invention will be further described in detail below with reference to the drawings and specific embodiments of the specification.
[0041] Such as image 3 As shown, the KCF-based UAV tracking method of the present invention includes:
[0042] Step S1: input image sequence;
[0043] Step S2: Use a coarse to fine search strategy to extract m image patches with the greatest similarity from the input image sequence;
[0044] Step S3: Extract FHOG, grayscale, and CN features from m image patches, and record them as feature maps; use PCA-entropy weight method to reduce dimensionality of m feature maps;
[0045] Step S4: Find the image patch corresponding to the maximum value according to the KCF algorithm of context-aware correlation filter tracking (KCF algorithm of context-aware correlation filter tracking) for the reduced feature maps corresponding to the m image patches, which is recorded as FindImage;
[0046] Step S5: Perform a fine search on FindImage according to th...
