Curves Extraction in Images
We present a methodology for extracting processes of curves in images, using a statistical summary of the directional information given in measures of location, curvature and direction associated with the pixels that compose each curve.

El propósito principal es obtener medidas que sirvan como insumo para la reconstrucción de los procesos de curvas que sean de interés, en formato de vector, de manera que las curvas extraídas puedan ser almacenadas fácilmente y reconstruidas en base a pocos parámetros conservando información representativa de su curvatura en cada pixel. Como punto de partida se usa la información direccional obtenida a partir de la metodología de detección consistente de curvas, la cual comprende la descomposición de la imagen en un dominio direccional contenido en R^(2^k), con k∈ N. Para este tipo de datos se proponen criterios básicos para las medidas de resumen y se muestra la aplicación a cuatro casos de imágenes satelitales para la extracción de tramos de río en dichas imágenes.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Estadísticahttps://revistas.unal.edu.co/index.php/estad/article/view/48815Universidad Nacional de Colombia Revistas electrónicas UN Revista Colombiana de EstadísticaRevista Colombiana de EstadísticaMartínez, Zoraida (2015) Curves Extraction in Images.

We present a methodology for extracting processes of curves in images, using a statistical summary of the directional information given in measures of location, curvature and direction associated with the pixels that compose each curve. The main purpose is to obtain measures that serve as input for the reconstruction, in vector format, of a process of curves which are of interest, so that the extracted curves can be easily stored and reconstructed based on few parameters conserving representative information of its curvature at each pixel. As starting point, the directional information obtained from a methodology of consistent curves detection is used, which includes the decomposition of the image in a directional domain contained in ℜˆ(2ˆk), with k ∈ ℵ. Basic summary measures criteria are proposed for this type of data and the application to four cases of satellite images for extraction of sections of rivers in these images are shown. |
