2013 2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC)  
In this article we investigate the suitability of a manifold learning technique to classify different types of emphysema based on embedded Probabilistic PCA (PPCA).  ...  A quantitative comparison with a texture-based approach based on Local Binary Patterns and with an approach based on local intensity distributions shows that our method is competitive.  ...  In this article we propose a novel approach to classify different patterns of emphysema based on a probabilistic interpretation of the manifold in which each pattern is embedded.  ...

Rodrigo Nava, Boris Escalante-Ramírez, Gabriel Cristóbal, Raúl San José Estépar
2014 Medical and Biological Engineering and Computing  
In this paper, we propose a new emphysema classification framework based on complex Gabor filters and local binary patterns.  ...  The results have shown the effectiveness of our approach for quantifying lesions due to emphysema and that the combination of descriptors yields to a better classification performance.  ...  Also in [29] , the dataset was used with a technique based on an embedded probabilistic PCA that resulted in a precision of 69 %.  ...
