$Variational\; models\; for\; image\; colorization\backslash n\backslash nBy\; Jean-François\; Aujol,\; Institut\; Mathématique\; de\; Bordeaux\backslash n\backslash nIn\; this\; talk,\; I\; will\; present\; an\; exemplar\; based\; variational\; approach\; for\; image\; colorization.\; Although\; the\; proposed\; functional\; is\; not\; convex,\; an\; optimization\; scheme\; converging\; to\; some\; local\; minimum\; is\; derived.\; Comparisons\; with\; state-of-the\; arts\; methods\; demonstrate\; the\; interest\; of\; the\; approach.\; An\; extension\; unifying\; manual\; and\; examplar\; based\; approaches\; for\; image\; colorization\; is\; also\; proposed.\; The\; choice\; of\; the\; color\; space\; to\; work\; with\; is\; discussed\; (YUV,\; RGB,\; HSI,\dots ).\backslash nThis\; is\; some\; joint\; work\; with\; Fabien\; Pierre,\; Aurélie\; Bugeau,\; Nicolas\; Papadakis,\; and\; Vinh-Thong\; Ta.[$
