Detección de movimiento de vehículos en secuencias de video basados en la diferencia absoluta entre fotogramas y la combinación de bordes

Abstract

A method for motion detection in video sequences, through the combination of absolute differentiation between two frames (ADF) and the analysis of edges in the motion region in the frame at time t is presented. This allows solving some disadvantages of the ADF by joining regions that belong to a single object in motion. The images, that are considered to be objects of interest, undergo morphological operations to remove objects with connected components that fall below a given threshold. A second absolute differentiation of frames is carried out considering only specific regions with the first differentiation motion, so that after combining the edges with the motion detection of the second absolute difference, the foreground image is obtained. The algorithm developed has the advantage of depicting the shape and the main parameters that define the object in motion.
