dc.descriptionA method was developed to characterize brain tumors in magnetic resonance images (MRI) using Gabor filters. This technique allows for obtaining a comprehensive set of features that accurately describe the image’s texture based on the direction, frequency, and amplitude of patterns present in the regions of interest. The characterization is based on Gabor coefficients and involves calculating a texture feature vector or histogram for each point in the image, classifying it as belonging to a tumoral region or not. To improve performance in characterization, preprocessing filters are applied to the input images, and postprocessing filters are applied to the Gabor coefficients. The results show that FLAIR (Fluid-Attenuated Inversion Recovery) sequence images are more suitable for obtaining the texture feature vector, which is subsequently used to identify tumor regions.en-US
dc.descriptionSe desarrolló un método para caracterizar tumores cerebrales en imágenes de resonancia magnética (IRM) mediante el uso de filtros de Gabor. Esta técnica permite obtener un conjunto exhaustivo de características que describen con precisión la textura de la imagen en función de la dirección, frecuencia y amplitud de los patrones presentes en las zonas de interés. La identificación se basa en los coeficientes de Gabor y consiste en calcular un vector propio de textura o histograma para cada punto de la imagen, clasificándolo como perteneciente o no a una región tumoral. Para mejorar el desempeño en la caracterización, se aplican filtros de preprocesamiento a las imágenes de entrada y filtros de posprocesamiento a los coeficientes de Gabor. Los resultados muestran que las imágenes de la secuencia de FLAIR son más adecuadas para obtener el vector característico de textura que se utiliza posteriormente para registrar zonas tumorales.es-ES
