Defocus Magnification
A blurry background due to shallow depth of field is often desired for photographs such as portraits, but, unfortunately, small point-and-shoot cameras do not permit enough defocus because of the small diameter of their lenses. We present an image-processing technique that increases the defocus in an image to simulate the shallow depth of field of a lens with a larger aperture. Our technique es...
متن کاملForbidden Magnification ?
The twin of this paper, “Forbidden Magnification? I.” [1], presents systematic SOM simulations with the explicit magnification control scheme of Bauer, Der, and Herrmann [2] on data for which the theory does not guarantee success, namely data that are n-D, n > 2 and/or data whose components in the different dimensions are not statistically independent. For the unsupported n = 2 cases that we in...
متن کاملCosmic Magnification
I present the current status of the cosmic magnification produced by systematic amplification of background sources by large-scale structures. After introducing its principle, I focus on its interests for cosmology and underline its complementary aspect to cosmic shear and galaxy auto-correlations. I finally discuss recent investigations using higher-order statistics.
متن کاملMagnification for the dermatologic surgeon.
Ergonomic practice increases the productivity, quality, and longevity of the dermatologic surgeon. When used properly, magnification devices can be ergonomic and beneficial additions to the dermatologic surgeon's practice. Herein, we review the available magnification options for the dermatologic surgeon and evaluate the options based on cost, design, and functional advantages and disadvantages...
متن کاملDopaminergic Gene Polymorphisms Affect Long-term Forgetting in Old Age: Further Support for the Magnification Hypothesis
Emerging evidence from animal studies suggests that suboptimal dopamine (DA) modulation may be associated with increased forgetting of episodic information. Extending these observations, we investigated the influence of DA-relevant genes on forgetting in samples of younger (n = 433, 20-31 years) and older (n = 690, 59-71 years) adults. The effects of single nucleotide polymorphisms of the DA D2...
