How can I blend the edges form a foreground to a background ?

[Tormy]

This is the situation

I want to blend the foreground (right side) to the background (left side) with a blur. 

Is there a way? (yes I know I can copy and paste the selection and blur it but I'm wondering whether there is another more rapid method)

 

EDIT: I want to blur ONLY the edge of the above picture

Apply a Gaussian blur to the right-hand object, and then increase the size of the object so that its blurred edges extend beyond the top, bottom, and right-hand edges of the canvas. As long as that object is clipped to the canvas, you won’t see the blurred edges on those three sides.

if I do so, the whole object is blurred and this is what I no want.

it didn't work. Perhaps did I wrong something? I added a pixel layer right above and I used the inpainting brush ... nothing changed.

Just mask it out?

This seems unclear. Do you want a fading edge, which can be created with a blur but doesn't have to be – or do you want to fade/blend the image AND blur the faded area additionally?

For the first the Transparency Tool may be the easiest solution, as mentioned by @carl123. If the image is a layer of type 'Pixel' you may convert it to an 'Image' layer.

Also a nested rectangle shape with a blur layer effect as a masking object is an easy solution.

In case of the latter – fade PLUS blur – you'll need your mentioned solution with a copy of the image layer.

Do you mean something like that?

1. Are you sure you specifically want a blur?
2. Do you want to blur on alpha channel only, or a blur on color channels?
3. Would a gradient on transparency be ok (a blur creates such gradients, but has the potentially unwanted side effect of blurring colors and distorting edge curvature)
4. Do you want to blend only straight lines? What should happen at corners? What on non-straight edges?
5. what is „more rapid“ for you? You mentioned selection, copy/paste (or duplicate?), and blurring, so about 3 steps.
6. should it work non-destructive or destructive?
    

Your question can be interpreted in a million ways and we don’t know your workflow preferences. If you say

Nobody knows what you actually did.

So please provide at least:

1. the actual file with a test case (saved with history)
2. a screen recording what you edit workflow is know, showing the steps, and the final result

otherwise you create a perfect storm of replies based on wild guesses of your intentions and you can reject every reply forever.

I wanted to get this:

And this is called BLUR
And this is only for the edge
As I asked in my topic.
And till now unfortunately the suggestions didn't work.
When you say "no oen knows what you did" is not true: Because I applied all the suggestions they gave to me and nothing worked as I wished.

No problem .. I applied the "workaround" I described in my opening.

Not really faster but non-destructive without a copy of the image with a 'copy of blur' instead (one for the image, the other for the mask). (V1)

Here’s another technique that might be worth experimenting with, in Photo (or Publisher’s Photo Persona).

With the ‘foreground’ layer selected:

1. menu “Select → Selection From Layer”;
2. menu “Select → Outline…”,set a Radius (.e.g 40 pixels), and Apply;
3. menu “Select → Feather…”, set a Radius (.e.g. 20 pixels), and Apply;
4. add a “Gaussian Blur Live Filter” and set a Radius (e.g. 10 pixels);
5. menu “Select → Deselect”.

(You can try different types of Blur Live Filter to see which one looks best.)

The original ‘foreground’ layer remains as it was, the blur can be altered to suit, and the whole effect can be temporarily ‘switched off’ if necessary.

However, if the original ‘foreground’ layer changes position or size then the blur effect will need to be recreated.

See attached video for an example.

THIS worked perfectly out! Thank you a lot!

You're welcome.

If you want to repeat such edges multiple times, here is a more flexible, non-destructive workflow with editable edge width instead of pixel selection, which can therefore be applied to different image sizes and aspect ratios.
