Abstract

La presente invención corresponde a métodos para la descripción de una imagen de campo visual. Particularmente con métodos para la descripción del resultado de una prueba de campo visual que entrega un analizador automático de campo visual. Uno de los métodos de descripción de una imagen de campo visual divulgados comprende las etapas de obtener un mapa gráfico de probabilidad de la imagen de campo visual, definir niveles de significancia estadística, generar una primera matriz de acuerdo con los niveles de significancia estadística y el mapa de probabilidad, generar una segunda matriz de acuerdo a un método de crecimiento de región y generar una lista con unos resultados de clasificación con un método de clasificación multiclase. El dispositivo para la descripción de campo visual, que comprende una unidad de cómputo de propósito específico; y una unidad de adquisición de imágenes conectado a la unidad de cómputo, en donde la unidad de cómputo está configurada para ejecutar las etapas de cada uno de los métodos divulgados.The present invention pertains to methods for describing a visual field image. Particularly with methods for the description of the result of a visual field test delivered by an automatic visual field analyzer. One of the disclosed visual field image description methods comprises the steps of obtaining a graphical probability map of the visual field image, defining levels of statistical significance, generating a first matrix according to the levels of statistical significance and probability map, generate a second matrix according to a region growth method and generate a list with some classification results with a multiclass classification method. The device for visual field description, comprising a specific purpose computing unit; and an image acquisition unit connected to the computing unit, wherein the computing unit is configured to execute the steps of each of the disclosed methods.
