I took some picture this summer and one of the subject does have very clear eyes and so he is subject to redeye. I try to use digikam tool to remove them but there are absolutely no visible difference in the before and after image. I try to change the Red level but it doesn't have any effect and I am not sure what is the usage of the channel and curve. I am probably not using the tool properly but I am probably not the only one in this case. I try to use the redeye removal tool from The Gimp and it worked correctly. I can send the picture but I will prefer to not put them on a public website. I am sorry but there are privacy issue here. Thanks for digikam, it is a great tool.
You can send me a test image to my private email address. Maik
Thanks for the test image. The openCV face detection does not recognize the face in the image, therefore, also no recognition of the red eyes. The face is slightly in profile. Just take a look... Maik
Perhaps the tool is a little bit too sophisticated and another option where selecting the eye and detecting an ellipse with red-ish color can be a good addition but perhaps you will be able to improve the automatic detection which will be very helpful for most of people. Thanks to look at the problem.
A manual patch will not be able to run in batch with all automatized workflow. The algorithm to detect the face and red eyes need to be improved. We have a student working on face recognition while this summer who make great Face Management improvements. He is a mathematician, so certainly he can take a look if time permit. I will CC him.

Lui, I CC you about this entry, to see if you can take a look in the algorithm for some face detections improvements (including eyes). Thanks in advance Gilles Caulier
Hulufr, Can you share the problematic image somewhere in cloud for future investiguations ? Thanks in advance. Gilles Caulier
