Le colloque GRETSI’27 s\u2019articule autour de sept grands th\u00e8mes scientifiques, communs aux diff\u00e9rentes \u00e9ditions du colloque, qui couvrent les principaux domaines du traitement du signal, des images et des sciences de l\u2019information et de la communication.<\/p>\n\n\n\n

Des sessions sp\u00e9ciales, propres \u00e0 l\u2019\u00e9dition 2027, viendront compl\u00e9ter ce programme scientifique. Elles seront annonc\u00e9es prochainement.<\/p>\n<\/section>\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n
