Abstract
EL PROCEDIMIENTO Y EL CIRCUITO ESTAN DESTINADOS A TRATAR UNA IMAGEN REPRESENTADA POR PIXELS OBTENIDOS POR BARRIDO POR COLUMNA DE BANDAS DE ALTURA IGUAL A UNA FRACCION ENTERA DE LA IMAGEN. SE RECORTA LA IMAGEN EN BLOQUES DE N COLUMNAS DE M PIXELS. SE DETERMINA LA DISTORSION GLOBAL MINIMA POR COMPARACION ENTRE CADA UNO DE LOS BLOQUES DE LA IMAGEN EN CURSO A SU VUELTA Y CADA UNO DE LOS BLOQUES DE IGUAL TAMAÑO EN UNA VENTANA DE BUSQUEDA DE H LINEAS Y L COLUMNAS EN LA IMAGEN PRECEDENTE, VENTANA QUE CONTIENE DICHO BLOQUE DE LA IMAGEN EN CURSO, EFECTUANDOSE ESTE CALCULO EN M.N CICLOS POR CALCULO EN PARALELO, DURANTE CADA CICLO, DE TODAS LAS DISTORSIONES PARCIALES ENTRE UN PIXEL DETERMINADO DEL BLOQUE EN CURSO Y CADA UNO DE LOS PIXELS QUE PURDEN CORRESPONDERLE POR DESPLAZAMIENTO DEL BLOQUE EN LA VENTANA DE BUSQUEDA DE LA IMAGEN PRECEDENTE, REPITIENDOSE EL CICLO PARA CADA PIXEL DEL BLOQUE A SU VUELTA. FINALMENTE, SE DETERMINA CUAL DE LOS BLOQUES DE LA IMAGEN PRECEDENTE TIENE MENOR DISTORSION EN RELACION AL BLOQUE DE LA IMAGEN EN CURSO.
