HLS Noise Ino\medskip

\par

\normalsize

Add pixel noise to the Hue, Lightness, Saturation, and Alpha.\par

The addition of noise adjustment to the cell picture, has been developed\par

for the purpose of adapting the picture of the background.\\

\par

The Alpha channel will determine the strength of the noise. Therefore,\par

smooth edges will remain smooth.\par

The strength of the Alpha channel itself will also affect noise, check the value.\\

\par

When you check the results, please do not use the sub-camera.\par

This is because in the sub-camera the range of the input image is different,\par

the noise pattern will change.\\

\\

-{-}- \ Inputs \ -{-}-\\

Source\par

Connect the image to process.\\

Reference\par

Connect the reference image to put the strength of the effect into each Pixel.\\

\\

-{-}- \ Settings \ -{-}-\\

Hue\par

Specify the strength of the noise for the color (Hue).\par

Pixel value (8 or 16bits) specified as a value from 1 to 0.\par

Minimum value is 0, maximum value is 1.\par

It does not apply the noise to the color (Hue) when the value is 0.\par

The default value is 0.025.\\

\\

Lightness\par

Specify the strength of the noise for the brightness (Lightness).\par

Pixel value (8 or 16bits) specified as a value from 1 to 0.\par

Minimum value is 0, maximum value is 1.\par

It does not apply the noise to the brightness (Lightness) when the value is 0.\par

The default value is 0.035.\\

\\

Saturation\par

Specify the strength of the noise for the chroma (Saturation).\par

Pixel value (8 or 16bits) specified as a value from 1 to 0.\par

Minimum value is 0, maximum value is 1.\par

It does not apply the noise for the chroma (Saturation) when the value is 0.\par

The default value is 0.0.

\ \vspace{-0.2em}

\par

\noindent Alpha\par

Specify the strength of the noise for the Alpha channel.\par

Pixel value (8 or 16bits) specified as a value from 1 to 0.\par

Minimum value is 0, maximum value is 1.\par

It does not apply the noise to the Alpha channel when the value is 0.\par

The default value is 0.0.\\

\\

Seed\par

The value of the order to determine the random noise pattern of the image.\par

Specify an integer value greater than or equal to 0.\par

If this value is the same, it will reproduce the same pattern.\par

It will be a different pattern If you add the noise with a different value.\par

The default value is 1.\\

\\

NBlur\par

It blurs the noise component, reduces the dot  impression.\par

Minimum value is 0, maximum value is 1.\par

Because it is calculated only in pixels adjacent to the dot,\par

it will feel like a very light blur.\par

When the blur value is not 0, it will take the average of the pixels adjacent\par

to each other up to a value of 1.0.\par

The default value is 1.\\

\\

Limits\par

The brightness (Lightness), chroma (Saturation), opacity (Alpha),\par

adjustment to effect the end value (in the vicinity of 0 to 1).\par

Applying the noise at 0 or near 1, will appear below 1 or more than the value of 0,\par

so it can not be expressed, because the values are each truncated to 0 or 1.\par

It is effective to compensate for the truncation.\par

-{-}> \textquotedbl End value of Noise effect adjustment \ \ Figure 1 \ \ comparison\textquotedbl \ reference\par

-{-}> \textquotedbl End value of Noise effect adjustment \ \ Figure 2 \ \ description\textquotedbl \ reference\\

\par

\noindent \ \ \, Effective\par

Determines the strength of this effect (Limits).\par

It has no effect if the value is 0. Effect a table using a value greater than 0\par

A value of 1 will have the strongest effect.\par

The default value is 0.\\

\par

\noindent \ \ \, Center\par

Determines the center of the effect.\par

Noise range deviation, the effect of the reduction of the noise width, most strongly\par

at the portion of 0 to 1 of the end value, will have no effect in the center.

\newpage

\thispagestyle{empty}

\ \vspace{-0.2em}

\par

Position the center value without this effect.\par

The value must be between 0 and 1.\par

If the value is 0, it will have no effect on a Pixel with a value of 0.\par

If the value is 1, it will have no effect on a Pixel with a value of 1.\par

The default Center value is 0.5.\\

\par

\noindent \ \ \, Type\par

Select from the options of the Type of the effect.\par

If you select \textquotedbl Keep Noise\textquotedbl , it maintains the (overall) noise width shifting of the\par

noise range, the contrast of the entire image will shrink.\par

If you select \textquotedbl Keep Contrast\textquotedbl , it maintains the contrast to reduce the noise width\par

only at the end.\par

The default setting is \textquotedbl Keep Noise\textquotedbl .\\

\\

Premultiplied\par

When ON, RGB is already set to Premultiply\par

(The value of Alpha channel is multiplied in advance RGB channels)\par

and processes as an image.\par

At that time, and added to the Alpha processing, you may not get the correct image.\par

The default setting is ON.\\

\\

Reference\par

Choose how Reference image values put the strength of the effect into each Pixel.\par

An image is connected to the \textquotedbl Reference\textquotedbl \ of the input,\par

Choose from Red/Green/Blue/Alpha/Luminance/Nothing.\par

Choose Nothing when you do not want this effect, it will turn off the connection.\par

The default setting is Red.
