Fisher kernel image processing
WebAug 24, 2024 · 2.2 The Fisher Kernel. Fisher kernels provide a systematic way of using the parameters of the generative model to define an embedding space for kernels capable of being deployed in discriminative classifiers. The Fisher kernel finds out the similarity between any two examples, \mathbf {x}_i and \mathbf {x}_j as follows: http://www.cs.ucl.ac.uk/fileadmin/UCL-CS/research/Research_Notes/RN_11_06.pdf
