Hybrid Generative-Discriminative Generalized Dirichlet-Based Hidden Markov Models with Support Vector Machines
Samr Ali, Nizar Bouguila · 2019
Recent years have witnessed tremendous advancement in data modelling. In this paper, we focus on Dynamic textures (DT). We propose the use of Fisher kernels with Generalized Dirichlet based hidden Markov models (HMM) for DT recognition. Experiments demonstrate promising results on the DynTeX Alpha dataset using the proposed generative discriminative approach. This is the first application of Generalized Dirichlet HMMs to DT recognition, to the best of our knowledge.
