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 ... -
Intelligent Surveillance Systems: A Review
Mejia, Jose (2020-12-01)La seguridad es la percepción que se tiene en algún entorno, de estar protegido, sin miedo a sufrir algún daño. Este documento ofrece una revisión de literatura sobre el tema de seguridad inteligente, basada en técnicas ... -
PET Image Reconstruction Using a GRU-Convolutional Network
Mejia, Jose (2022-10-24)Positron emission tomography is widely used for tumor detection and treatment monitoring in oncology. However, the quality of the images depends, among other factors, on the amount of radiopharmaceutical ingested by the ... -
Reconstruction of PET images using anatomical adaptive parameters and hybrid regularization
mejia, jose (2018-04-01)Positron Emission Tomography (PET) is a nuclear medicine technique used to obtain metabolic images of the body. PET scanners used in the research, treatment, and monitoring of several diseases provide images of metabolic ... -
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 ...
