Embodiment Construction
[0032] Various details involved in the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.
[0033] The category-dependent codebook generation method generates a specific codebook for each category of images, so that the coefficient values of the same category of images mapped to this type of codebook are large and show certain regularity, while other categories of images map The coefficients assigned to such codebooks will be relatively small and irregular.
[0034] The classifier ij that classifies the image of the i class and the image of the j class uses the vector link obtained by the training image of the i class in the category-related codebook and the class-related codebook as the training image vector of the i class, and classifi...
