[Plugin] "Red-Eye" removal

[michaeld]

Hi!

At this URL http://www.deindl.name/ASP-plugins/ you can download a first version of a "Red-Eye" removal plugin.

Usage:
1. Select the red pupil with a circle-layer. For best result make that circle as small as possible and set the "Feather" to the minimal value.

2. Check the "Enable" checkbox of the plugin.

What the plugin does is to replace the red-channel of a pixel with the average value of the blue and green channels, IF the red-channel is bigger than 1.5 times this average.

This is the first version of my plugin so a few things are left to do:
* Add controls for sensitivity and darkness of the pupil
* Translate to other languages
* Deal with animal eyes

Bye,
Michael

Edit: changed URL

Hi!

Here, tested on several linux computers with different OS and DE flavours, this plugin doesn't show up after the installation.
Anyone seeing the same?

When reinstalled, an error is given:
"
/home/lars/Downloads/Plugins/AfterShot/mdRedEyes.afzplug

Unable to uninstall existing plugin: mdRedEyes.afplugin
Unable to delete /home/olmur/C/Aftershot/mdRedEye/windows-mac-readme.txt

Please contact the plugin author.
"

A PM with the logfile is on its way to the developer.


Cheers,

I tried loading it on my Win7 machine...

ASP indicates it is there, but I don't see it under either "Plugins1" or "Plugins2". I noticed I have 5 plugins each installed under those two tabs (10 plugins total). Is there a limit to how many plugins you can load in ASP, or how many in each tab?

When I look at my log file, the plugin section starts as follows:

Note that there is one plugin that has no name ... I would bet money (if I had any ) that this is our red eye tool

Hi!

There is some minor building error in the plugin. It has an internal plugin identifier, name.deindl.mdRedEyes, but this one apparently doesn't register when ASP starts.

If one in the Info.afpxml file changes the wrong path given for windowsLibFile="/home/olmur/C/Aftershot/mdRedEye/windows-mac-readme.txt" to windowsLibFile="" then it loads correctly and shows up in the plugin tabs, even though it still doesn't register itself in ASP.

Hi!

Thanks for your feedback.

I should have mentioned that it currently only runs on Linux. Windows and Mac versions are planned, assuming I find somebody to compile it for me.

I uploaded a new version 1.0.1 of my plugin to home.bawue.de/~olmur/plugins/mdRedEyes.afzplug
It fixes the deinstall problem and the log shows it's registering:

Name: mdRedEyes
Identifier: name.deindl.mdRedEyes
   Version: 1.0.1
      Path: <User Home>/Plugins/mdRedEyes.afplugin

@FotoLars: thanks for your PM. Unfortunately I seem to be unable to reply.

Hi,

cool, works here on my Linux box.

Great!

But you will need to remove manually the earlier 1.0.0 directory from ~/.AfterShotPro/Plugins - is this hard coded into the manifest?

Hm, there are images which get green eyes with the plugin. I think the resulting colour should be always gray:

Rnew = Gnew = Bnew = (R*sr+G*sg+B*sb)/3*sd

sr, sg, sb are sliders for the colors
sd slider for the darkness in the result

Initial values may be sr=0.2, sg=1, sb=1, sr=1 to nearly eliminate the red channel. For animals perhaps sr=1, sg=0.2, sr=0.8 which can be set up by presets.

This may arise when the plugin identifier changed or perhaps when ASP does not recognised the plugin in the former version. ASP should remove all what is included in the Info.afpxml file resp. the whole folder on an update.

Hi!

I uploaded version 1.1.0 to http://home.bawue.de/~olmur/plugins/mdRedEyes.afzplug. Details below.

You are right. I missread a paper about read-eye removal.

[quote="andreas]Initial values may be sr=0.2, sg=1, sb=1, sr=1 to nearly eliminate the red channel. For animals perhaps sr=1, sg=0.2, sr=0.8 which can be set up by presets.[/quote]
Good suggestion. Have to think a bit how to arrange the UI for that (without using too much space).

The new version has sliders "Sensitivity" and "Luminance". The algorithm to "remove" red eyes is:

Code: Select all

mean_green_blue = (green + blue) / 2
If (red >= ((sensitivity * mean_green_blue) / 100):   R = G = B = (mean_green_blue * Luminance) / 100

In other words: "Sensitivity" says how much the red-channel has to dominate a pixel to be seen as red eye and luminance is a percentage of how luminant the corrected pixel will be.

Michael

Still only Linux?
