Abstract

EL CIRCUITO PARA LA ESTIMACION DEL MOVIMIENTO EN CODIFICADORES DE SECUENCIAS DE VIDEO NUMERADAS CONSTA DE AL MENOS UN COMPONENTE DE CIRCUITO INTEGRADO (IM, IM1.LMN) QUE ESTA DISPUESTO PARA EJECUTAR LA FUNCION DE DETERMINAR LOS VECTORES DE MOVIMIENTO Y LOS COSTES ASOCIADOS PARA LOS DISTINTOS MODOS DE PREDICCION O LA FUNCION DEL AFINADO DEL VECTOR, POSIBLEMENTE JUNTO CON LA SELECCION DEL MODO DE PREDICCION. EL CIRCUITO (IM) SE BASA EN EL USO DE DOS UNIDADES OPERATIVAS (M1, M2) QUE ESTAN DISPUESTAS PARA PROCESAR SIMULTANEAMENTE DE DISTINTAS FORMAS GRUPOS DIFERENTES DE PIXELES DE ACUERDO CON UNA TECNICA MIMD. PREFERENTEMENTE, CUANDO EL CIRCUITO EJECUTE LA DETERMINACION DEL VECTOR DE MOVIMIENTO, LAS UNIDADES OPERATIVAS (M1, M2) SE PROGRAMAN PARA EJECUTAR UN ALGORITMO GENETICO QUE EXPLOTA UNA POBLACION DE VECTORES INICIALES QUE TIENEN EN CUENTA LAS CORRELACIONES TEMPORALES Y ESPACIALES EN LA IMAGEN.
