Can we generate “foveated Image” in Mathematica

Question

\"Foveated imaging is a digital image processing technique in which the image resolution, or amount of detail, varies across the image according to one or more \"fixation po

Answer 1

Something along the following lines may work for you. The filtering details should be adjusted to your tastes.

lena = ExampleData[{"TestImage", "Lena"}]

ImageDimensions[lena]

==> {512, 512}

mask = DensityPlot[-Exp[-(x^2 + y^2)/5], {x, -4, 4}, {y, -4, 4}, 
                    Axes -> None, Frame -> None, Method -> {"ShrinkWrap" -> True}, 
                    ColorFunction -> GrayLevel, ImageSize -> 512]

Show[ImageFilter[Mean[Flatten[#]] &, lena, 20, Masking -> mask], ImageSize -> 512]
