Abstract
EL INVENTO TRATA DE UN PROCEDIMIENTO QUE PERMITE RECONSTRUIR LOS VALORES DE LUMINANCIA DE UNA TRAMA (TJ) A PARTIR DE LOS VALORES DE LUMINANCIA DE LOS PIXELES DE DOS TRAMAS CONOCIDAS (TA,TB). CONSISTE ESENCIALMENTE EN : ESTIMAR UN VECTOR VELOCIDAD (V ) PARA CADA PIXEL (G) DE UNA UNICA TRAMA (TI) CORRESPONDIENDO EN UN INSTANTE TI COMPRENDIDO ENTRE TA Y TB O SIENDO TA O TB. - DETERMINAR SUCESIVAMENTE PARA CADA PIXEL (G) DE ESTA IMAGEN (TI), DICHO PIXEL PADRE, LAS COORDENADAS DEL CENTRO (FJ) DE UN PIXEL A INTERPOLAR (H), DICHO PIXEL HIJO QUE CORRESPONDE AL CENTRO (CI) DEL PIXEL PADRE POR UNA TRASLACION CUYO VECTOR ES FUNCION DEL VECTOR VELOCIDAD (V) DEL PIXEL PADRE, MULTIPLICADO POR LA DURACION TI-TJ; -ASOCIAR SUCESIVAMENTE A CADA PIXEL A INTERPOLAR (H) UN VECTOR VELOCIDAD QUE ESTA CONSTITUIDO POR EL VECTOR VELOCIDAD (V) DE SU PIXEL PADRE (G); DETERMINAR EN LAS DOS TRAMAS CONOCIDAS (TA,TB) LAS COORDENADAS TRAS LA LUMINANCIA DE DOS PUNTOS (A,B0 CORRESPONDIENTES AL CENTRO (FJ) DEL PIXEL A INTERPOLAR (H), POR UNA TRASLACION EN EL PLANO DE UNA DE LAS IMAGENES CONOCIDAS (TA,TB), TRASLACION CUYO VECTOR ES FUNCION DEL VECTOR VELOCIDAD ASOCIADA AL PIXEL A INTERPOLAR, MULTIPLICADA RESPECTIVAMENTE POR LAS DURACIONES TJTA Y TB- TJ; - DETERMINAR UN VALOR DE LUMINANCIA PARA EL PIXEL A INTERPOLAR (H), CALCULANDO UNA COMBINACION LINEAL DE LOS VALORES DE LUMINANCIA DE ESTOS DOS PUNTOS (A,B). SE APLICA A LOS CAMBIOS DE NORMA DE LAS IMAGENES DE TELEVISION Y EN LA RECOMBINACION DE IMAGENES QUE FALTAN EN UNA TRANSMISION DE IMAGENES CON BAJO FLUJO CON SUPRESION DE CIERTAS IMAGENES.
