Comparación de Técnicas de Procesamiento de Video en Diferentes Espacios de Color para la Estimación de la Frecuencia Cardíaca
Cota Ruiz, Juan De Dios; Mederos, Boris; Rascon Madrigal, Lidia Hortencia; Mejia, Jose; Díaz Román, José David; 158173; González, Daniela (Sociedad Mexicana de Ingeniería Biomédica, 2021-11-30)This study aims to compare different analysis techniques to determine which of these provides better results in estimating heart rate through video processing. The techniques, in general, consisted in the extraction of ... -
Feature space optimization for brain tissue classification in non-contrast computed tomography images
Mejia, Jose; Mederos, Boris; Gordillo Castillo, Nelly; Sánchez Guerrero, César Ubaldo; Cruz Aceves, Iván (IEEE, 2021-09-13)In this work, a classification problem focused on brain tissue types in non-contrasted computed tomography images is explored. A group of characteristics is proposed in the spatial domain, and block model for feature ... -
Hyperdense Middle Cerebral Artery Segmentation in Non Contrast Computed Tomography
Gordillo Castillo, Nelly (Springer, 2018-05-30)The hyperdense middle cerebral artery (MCA) sign refers to focal increased density of the MCA in Non-Contrast Computed Tomography (NCCT) and is the earliest sign of acute ischemic stroke. In this paper, we present the ... -
Identification of Pneumonia with X-ray Images Using Deep Transfer Learning
Díaz Román, José David (Springer, 2023-10-26)Radiology plays an essential role in the identification of pathologies; however, image interpretation and the guarantee of accurate diagnoses continue to represent a challenge that involves expert radiologists. This study ... -
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 ... -
