In general, blind image restoration is an ill-posed inverse problem which recovers the latent image
from the blurred observation without any knowledge about the blurring process .
20 banknotes in Mahatma Gandhi Series- 2005 issued recently with the ascending size of numerals in the number panels, without intaglio printing, without latent image
, and without identification mark.
The latent image
is always visible in something other than intaglio.
This drive to archive the artifacts from the past would be familiar to readers of graphic novels such as Art Spicgelman's Mans, and Weaver's memoir similarly reaches 1hr both recovery and reckoning, where some of the story--about immigration, about race, about identity--is beyond her immediate experience: what she terms "the latent image
On the obverse side of ` 500 note, a vertical band on the right side of the Mahatma Gandhi's portrait contains a latent image
showing the respective denominational value in numeral
In current radiography, latent image
of an X-ray exposed object is produced when X-rays strike silver bromide crystals in the film emulsion; they can only absorb a very small amount of X-ray energy to convert them into a latent image
He said security features, such as see through, security threads, watermarks (Quaid-e-Azam Mohammed Ali Jinnahs portrait), latent image
, anti-copy / anti-scanning line patterns in our new currency note series are in place to minimize the chances of producing or printing of counterfeiting by unscrupulous elements.
This spatial localization (electrostatic charges) corresponds to the latent image
(charged light image) on the drum.
The latent image
is the difference of potentials of two extreme voltages the: -700V of the free surface (formed in the charging phase) and -100V printing elements (formed during laser imaging) (Severens, 2004).
Computed radiography (CR) was the product name for the first commercial device for making radiographs using the process of photostimulable luminescence (PSL), whereby X-ray energy projected onto a doped crystalline material--the photostimulable phosphor (PSP)--produces a latent image
of excited electrons in local potential energy traps.
Following exposure, a reading device uses laser light to release the captured latent image
and convert it into a conductive band of green, blue or ultraviolet light called "photostimulable luminescence.
