Removing stripes very very ugly

[limaze]

hello everyone. i have very trouble getting rid of vertical lines in some of my pictures. do you know of a way to remove the stripes without extensive use of blur and without losing detail?


in first attached picture you can clearly see the troublemaker; second picture is my try with neatimage, but as you can see stripes are still there and i lost some details.


it would be great if anyone know good way to deal with those lines, have a nice day!

An interesting problem. I admit I haven't solved it but what helped some was to do the following.

Copy the layer. Then select darken for the blending mode. Select the move tool and click the right arrow three times. That moves the darker stripes over the lighter ones..

Thats the start. Then use the various blurr filters using darken or lighten blending modes

It was a small picture to work with, needed a larger picture really, anyhow, i worked on the face, yes its lighter, but don't ya know wrinkles are not usually downwards...(I could tell a joke here but i wont) Anyhow nice smiley eyes you got. Great picture, if you want to use this your welcome, but i didnt do the ears.

I tried a variation of Flora's tutorial on Remove Photo Paper Texture From
Old Photos. You can follow her excellent instructions found in the Tutorial Section of the site.

I did deviate from her tutorial in the following ways:

1. I increased the Y setting in Neat Image to 90%
and I followed her settings for the Gaussian Blur layer.

2. I painted back in the detail in the eyes, lips, creases just as she directs.

3. I then Merged Visible and added some skin texture since the Neat Image
and Gaussian Blur made him very smooth. Don't forget to add noise as
she lists in the instructions.

4. For the texture I selected Filter>Stylize>Emboss with a setting of
Height-1 and Amount of 298, (299 would have been too much!).

5. I added an Empty Layer set to Softlight Blend Mode with a soft Black
brush went over the hair and shadows.

Sorry, something went wrong and I sent the wrong image, AHHHH.

hey this is great, thank you all for trying to fix the picture! hmm it seems those lines cannot be beaten without softening the image to an extent where most detail is lost. curse you stripes!

It might take some additional experimentation but here's what I came up with using Alex Chirokov FFT filter.

Dave, you did a great job there!
I have had the opportunity to exchange some PM's with limaze about this type of image and I must admit that I had advised him that it would be very difficult to use the FFT in this situation.
To me the little "stars" would get mixed up with the central horizontal line.
I took a different path but now I'll go back and rethink the FFT way.

I applied a High-pass and a GBlur at radius 1.0 to a duplicate layer. Inverted this, set blending to linear light and then increased the contrast until the stripes disappeared. Masked this, because some details also disappeared. Then masked in a new duplicate layer with GBlur 2.0 and some texture.

Duv, this is awesome, thats exactly what i was looking for. but how did you know what part of fft picture to modify?



hello byro! did you get my latest private message? its in unread status for a week now, i thought you were on vacation

Well I did a few more steps this time.

First I copied the layer to a new layer with the blend mode darken. Selected the move tool and clicked the right arrow x 3 to bring the dark bands over the light bands.
To this layer I applied a mask and painted in the various areas.

I copied this layer and ran neat image on it.

on a new layer above that using soft light I touched up a few areas.

Thanks Ro! Thanks Limaze!
When I initially looked at the FFT, I didn't think it would work either. I thought the secret was in cloning away most of the vertical and horizontal lines up to where the little stars appear. It helped in some ways but caused other problems. I couldn't believe the 2 little stars on the horizontal could cause all that grief but cloned them out anyway and voila.

Cheers

Here's another Neat Image effort. First pass, selected hair, inverted and ran filter. Second pass, added eyes to be protected and ran filter again. Then did some smudging to the skin.

Hi,

FFT was my first try here, but the results I got were a disaster until I saw what Dave managed to do with it!!!!
Thanks Dave for sharing your excellent results and the how-to ....

So I went back to FFT and in attachment 2 is the result I got with it.
To further 'clean' the image I used Neat Image very soft settings on the whole image first, and and the luminosity mask later. (didn't want to soften the image to much...)

I also took snapshots of my corrected Green and Blue Channels (the only ones I touched) during the FFT procedure. (attachment 3 and 4)

Hope this helps...

[Duv]

Thank you Flora!

What a great process when we can collectively work on a problem that results in what you finally achieved. It's no wonder I spend so much time here!

Thanks Dave .... spread all over the 'globe' and yet a great team.... I just looooove it!!!!!
