Embodiment Construction
[0040] In order to better understand the technical solutions of the present invention, the implementation manners of the present invention will be further described below in conjunction with the accompanying drawings. figure 1 It is a flow chart of the method for tracking small and weak moving objects based on sparse representation in the present invention. The detection algorithm obtains the target position of the infrared image, constructs the initial training samples and the initial particle set; uses the K-clustering singular value decomposition method K_SVD training samples to construct an over-complete dictionary of the adaptive morphological components of the image, and then uses the Gaussian over-complete dictionary to classify the adaptive morphological components On-line automatic classification of dictionary atoms, construct an adaptive online classification over-complete dictionary, that is, target over-complete dictionary and background over-complete dictionary, an...
