Abstract

UN DETECTOR PARA DETECTAR EL MOVIMIENTO DE UNA IMAGEN REPRESENTADA POR UNA SEÑAL DE VIDEO CONSTA DE MEDIOS DE RETARDO (40-52) PARA PROPORCIONAR DE MANERA CONCURRENTE LINEAS DE SEÑAL DE CINCO CAMPOS CONSECUTIVOS (A-E). LAS SUMAS (54) DE LAS SEÑALES (A3-B2) DE LOS CAMPOS PRIMERO Y SEGUNDO SE RESTAN (56) DE LAS SUMAS (58) DE SEÑALES (C3, D2) DE LOS CAMPOS TERCERO Y CUARTO PARA GENERAR UNOS PRIMEROS INDICADORES DE MOVIMIENTO (R2, R1). LAS DIFERENCIAS (62) DE LAS SEÑALES (A3, B3) DE LOS CAMPOS PRIMERO Y SEGUNDO SE RESTAN (64) DE LAS DIFERENCIAS (66) DE LAS SEÑALES (C3, D3) DE LOS CAMPOS TERCERO Y CUARTO PARA GENERAR SEGUNDOS INDICADORES DE MOVIMIENTO (R4, R5). LAS DIFERENCIAS (70) DE LAS SEÑALES (A3, E3) DE LOS CAMPOS PRIMERO Y QUINTO SON GENERADAS PARA FORMAR TERCEROS INDICADORES DE MOVIMIENTO (R7, R6, R5). SE COMPARAN (76) LOS INDICADORES DE MOVIMIENTO PRIMERO, SEGUNDO Y TERCERO Y EL MAYOR ES EL QUE CONSTITUYE UNA SEÑAL DE MOVIMIENTO QUE ES, POSTERIORMENTE LIMITADA, DESPLEGADA Y ESCALADA. LASSEÑALES UTILIZADAS PARA FORMAR LOS INDICADORES DE MOVIMIENTO SON SELECCIONADAS PARA RECHAZAR SUSTANCIALMENTE CUALQUIER INFLUENCIA ADVERSA DE LA SUBPORTADORA DE CROMINANCIA.
