Remove image from another image

Ok so I have 2 pictures, one is a picture of a cat's face, and the other is a picture of that cat's eyes (cropped from the face)

is there any way I can have photoshop remove every instance of the eyes(picture2) from the face (picture1)

note: I'm looking for the perfect match pixel to pixel not just any mouth


Example:

Welcome to RP, Dimava
I know many, if not most, folks do not have a utility which will open .rar files.
It would be easier if you could upload a jpg or bmp image in your message.
Regards, Murray

Hi Dimava
Welcome to Retouch Pro.

You can do that with calculations

Cameraken,

Thanks for the reply, and it seems very close to what I'm trying to accomplish. However whenever I try it, it just creates an alpha channel and leaves it at that. Also, I'm trying to remove the eyes, not just make them a darker color.... I think I'm doing something wrong with the calculations...

thanks,

Dimava

Hi dimava,

welcome to RP from me too!!

Could it be this?

Select the eyes and Ctrl+J copy the selection to a new Layer ..

Change the Blending of the new Layer to Difference which being 'none' it blacks out the eyes completely ...

Well Maybe you mean this way

Open Picture 1 and open Picture 2

Drag Picture 2 to picture 1 which places picture 2 on a new layer.

Align Picture 2 over the same area of picture 1. Use the difference blending mode until the top layer is black. Now they are perfectly aligned.

Command/Control windows Click Layer2 to select all of the pixels in layer 2.
Select layer 1 and delete.

Hi Dimava

I’m not really sure what you are trying to achieve here. I thought you were using those images as an example of method

You will still need to align the images first.
Set blending mode of the eye layer to difference.
Move and rotate the eye layer until it aligns with the cats eyes.
See layer1 in my layers palette

This may be enough for your needs as the difference mode will make the eyes black once they are aligned.

If not then change blending mode of eyes back to normal and use subtract.

It depends what you are trying to do.

Ken

Sorry, Let me re-explain what I'm trying to accomplish. I'm looking for a something similar to a "Find and Replace" function, except "Find and Remove".

For example if you go to Edit > Find in your internet browser and search for accomplish, it will highlight the word in my post. I'm looking for something similar in Photoshop.

I'm also using CS2 if that makes any difference.

thanks again

Hi Dimava

This is more difficult and cannot be accomplished with stock tools. You would have to read all the pixel values in the eyes picture and then search for the same pattern in the cat picture. And if you were searching for rotated patterns then the calculations could take ages.
You could write the code to do this but its far quicker to just use your eyeballs.

It would make an interesting project. But unless you have a specific, regular use for this it would hardly be worthwhile

Ken.
