    "abstract": "We analyze and realize the recovery, by means of spatial intensity\ncorrelations, of the image obtained by a seeded frequency downconversion\nprocess in which the seed field is chaotic and an intensity modulation is\nencoded on the pump field. Although the generated field is as chaotic as the\nseed field and does not carry any information about the modulation of the pump,\nan image of the pump can be extracted by measuring the spatial intensity\ncorrelations between the generated field and one Fourier component of the seed.",
