A fuzzy approach for feature extraction of brain tissues in Non-Contrast CT
Gordillo Castillo, Nelly (2018-01-15)In neuroimaging, brain tissue segmentation is a fundamental part of the techniques that seek to automate the detection of pathologies, the quantification of tissues or the evaluation of the progress of a treatment. Because ... -
Adaptive filter with Riemannian manifold constraint
Mejia, Jose (2023-06-02)The adaptive filtering theory has been extensively developed, and most of the proposed algorithms work under the assumption of Euclidean space. However, in many applications, the data to be processed comes from a non-linear ... -
Automated detection of parenchymal changes of ischemic stroke in non-contrast computer tomography: A fuzzy approach
Gordillo Castillo, Nelly (2018-06-05)The detection of ischemic changes is a primary task in the interpretation of brain Computer Tomography (CT) of patients suffering from neurological disorders. Although CT can easily show these lesions, their interpretation ... -
Characterization of Impulse Oscillometric Measures of Respiratory Small Airway Function in Children
Avila, Nancy (2019-03-01)Abstract. Children suffering from asthma are often undiagnosed or misdiagnosed as their symptoms are similar to other respiratory conditions. Spirometry, the "golden" pulmonary function test used for asthma di- agnosis, ... -
Computer-aided classification of small airways dysfunction using impulse oscillometric features: a children-focused review
Ávila, Nancy (2019-10-10)Abstract Background and objective Spirometry, which is the most commonly used technique for asthma diagnosis, is often unsuitable for small children as it requires them to follow exact instructions and perform extreme ... -
Reconstruction of Positron Emission Tomography Images Using Gaussian Curvature
mejia, jose (2018-11-15)Positron emission tomography (PET) provides images of metabolic activity in the body, and it is used in the research, monitoring, and diagnosis of several diseases. However, the raw data produced by the scanner are severely ... -
Which fourier components are most informative: General idea and case studies
Gordillo Castillo, Nelly (2019-05-01)In many practical situations, the information comes not in terms of the original image or signal, but in terms of its Fourier transform. To detect complex features based on this information, it is often necessary to use ...
