Pseudo-Color:
Myth or Reality?
Shaitan
To start let's parse this topic
First, consider the notion - PseudoColor. As the name implies
this technology, it is - the output image with imaginary
flowers, then there is a translation of the black-and-white
output format to a format with color information. Simply put,
it is a translation of black and white images in color.
And now a little history.
I remember when I was a little
(80 of the last century) and even
knew no such thing as a "computer", once in the "Times" spoke
of the that most bourgeois bourgeoisie decided all
your old movies converted to color
format. In a trial, they decided to take
film "Sun Valley Serenade" (there still
was such a funny song about locomotive Chatonoga Chuchu). The
film they worked about two years. All meaning of this
translation was the storyboard image, after which people hand
painted frames, and then this thing going in a heap, and
received a film with a color image. Thereby the global labor
engaged in such famous firm, as Kodak and Technicolor. Because
of the terrible complexity had to abandon the project. But
with the introduction of computer technology in
all areas of human inactivity
so no one dared to revive this project (perhaps from
insolvency, but may just in my head it has not yet occurred, who
them, the bourgeoisie, understand?).
Strictly speaking, we can now move
to the most important - the translation algorithm.
The essence of this algorithm was realized by me
after watching the next series of "Secret
Materials. "Algorithm translation in color
format is not very complicated and, yes, very much
strong resemblance to translate a color image to black and
white.
1. First we need to determine what percentage of the black
will match in color pure white (any image on non-digital media,
ie, photographs, slides, pictures, and then scan - have the
property eventually turn yellow) and pure black.
2. With black-and-white spectrum, we figured. Now, in order to
be able to manage the quality of translation of the image, we
necessary to divide the color flow on a certain number of
gradations, ie, give the number of colors used in the
matching using the number of shades of gray, which means
bringing the Each shade of gray to a specific
colors (shades).
3. And the last stage just take each point in black and white,
we can determine the level of its blackness, and in accordance
with it set already colored dot.
I think that you embraced the idea that I want to tell you.
But to keep transfer of images is necessary to satisfy certain
conditions:
1. To provide a better translation of the image, we need a
computer with a high specification video capability (ie one
that is able to give us the full picture of her beauty). For
example, such as high resolution. 2. Color necessarily have to
ask not for a group of points (as done in Speccy), and for each
point separately. This is due to the fact that if the color is
set for a group of points, then neodhodimo will interpolate
information about the color of all the points and take the same
color for the whole group, as a result we obtain
full cubism.
I think you completely understood what I wanted
to say (it is a multi-platform magazine). The Speccy, in my
opinion, this method generally applicable (sm.p.2), but suddenly
there is such a monster that will be solved
think of some glitch of this kind
and on the Spectrum. Let's hope that this
information will be helpful.
