Abstract

EN UN METODO PARA LA COMPENSACION DEL MOVIMIENTO DE IMAGENES DE VIDEO, SE DERIVAN UNA PLURALIDAD DE VECTORES DE MOVIMIENTO MEDIANTE TECNICAS TALES COMO UNA CORRELACION DE FASE ENTRE PARES DE IMAGENES. PARA PRODUCIR UN GRUPO DE VECTORES DE MOVIMIENTO QUE SE PUEDAN UTILIZAR PARA DEFINIR SUSTANCIALMENTE TODOS LOS MOVIMIENTOS EN UNA IMAGEN DE ENTRADA, LOS GRUPOS DE VECTORES SE DERIVAN DE COMPARACIONES ENTRE IMAGENES PRECEDENTES Y SUBSIGUIENTES Y DESPUES SE COMBINAN PARA PRODUCIR UN GRUPO DE VECTORES PARA ASIGNARLO A UNA IMAGEN DE ENTRADA. UNA VEZ DERIVADO EL GRUPO DE VECTORES ESTOS SON ASIGNADOS A LA IMAGEN DE ENTRADA DESDE DONDE SE PUEDE PROYECTAR PARA PRODUCIR UNA IMAGEN DE SALIDA DESEADA. LOS VECTORES SON ASIGNADOS A AREAS ELEMENTALES INDIVIDUALES DE LA IMAGEN Y CIERTAS AREAS ELEMENTALES TIENEN DOS (O MAS) VECTORES ASIGNADOS A ELLAS.
