Abstract
Un método para clasificar el tipo de toma de un cuadro de video, que comprende cargar un cuadro, dividir el cuadro en pixeles de campo y pixeles de no campo con base en un primer criterio de detección de campo de juego, determinar una clasificación de tipo de toma inicial utilizando el número de pixeles de campo y el número de pixeles de no campo, dividir el cuadro en una o más regiones con base en la clasificación inicial, determinar el estado de cada una de una o más regiones con base en el número de pixeles de campo y los pixeles de no campo ubicados dentro de cada región, y determinar una clasificación de tipo de toma para el cuadro con base en el estado de cada región.
