The next test you need to make is to see if Photoshop Autoalign layers will work on the two images stacked. If the can it should be quite easy to script the process.
Here I took and image layer duped it increased the canvas size lowered the opacity of the top layer and miss aligned the two layer. I used an action to target the visible layers and used Auto align layers to align the back. I use and action for auto align layers has a dialog that is not displayed when the action is played. You will also need to use scriptlistener code for autoalign layers in you script for there is no DOM interface for it.
I wrote a script for someone recently that processes pairs of files the files were in a single folder and the names sorted the file so the front and back images were next to each other. You could write a script like it the used one or two input folders and a single output folder. You would also save out PSD file not jpeg files. You would most likely open the first convert to a normal layer, expand the canvas some place in the second, rasterize the placed layer, target both layer and auto align layers.
The script I wrote to help someone process pairs of images.
#target photoshop
var savedRuler= app.preferences.rulerUnits; // Save Units
var orig_display_dialogs = app.displayDialogs; // Save dialog setting
app.preferences.rulerUnits = Units.PIXELS; // Work with pixels
app.displayDialogs = DialogModes.NO; // Set Dialogs off
var defaultFolder = "~"; // Default to desktop
var inputFolder = Folder.selectDialog("Choose a folder of images to process.", defaultFolder);
var outputFolder = Folder.selectDialog("Choose a folder to export resized images to.", defaultFolder);
var fileList = inputFolder.getFiles(/\.(nef|cr2|crw|dcs|raf|arw|orf|dng|jpg|jpe|jpeg|tif|tiff|psd|eps|png|bmp)$/i);
if (fileList.length%2===0) { // even number of files
for (var i = 0; i < fileList.length; i++) { // Loop through files
app.open(fileList); // Open First of Pair
app.activeDocument.trim(TrimType.TOPLEFT); // Trim
app.activeDocument.resizeImage(null,null,1200,ResampleMethod.NONE); // Resolution 1200
var h = app.activeDocument.height; // Height
var w = app.activeDocument.width; // Width
i++; // Next File
app.open(fileList); // open second of Pair
app.activeDocument.trim(TrimType.TOPLEFT); // Trim
app.activeDocument.resizeImage(null,null,1200,ResampleMethod.NONE); // Resolution 1200
var h1 = app.activeDocument.height; // Height
var w1 = app.activeDocument.width; // Width
var maxDim = Math.max (Math.max (w, w1), Math.max (h, h1)) +10; // max side plus border
app.activeDocument.resizeCanvas (maxDim, maxDim, AnchorPosition.MIDDLECENTER); // resize
if (app.activeDocument.name.lastIndexOf(".")!=0 ) { var Name = app.activeDocument.name.substring(0, app.activeDocument.name.lastIndexOf(".")); }
else {var Name = app.activeDocument.name;} // Document Name
var saveFile = outputFolder + "/" + Name ; // Output Path and File Name
SaveAsJPEG(saveFile, 10); // save second and close
activeDocument.close(SaveOptions.DONOTSAVECHANGES); // Close the just save
app.activeDocument.resizeCanvas (maxDim, maxDim, AnchorPosition.MIDDLECENTER); // resize
if (app.activeDocument.name.lastIndexOf(".")!=0 ) { var Name = app.activeDocument.name.substring(0, app.activeDocument.name.lastIndexOf(".")); }

var saveFile = outputFolder + "/" + Name ; // Output Path and File Name
SaveAsJPEG(saveFile, 10); // save and close First

Hello @SuperMerlin
Your javascript seems like exactly what I need. I can't get past this error:
I tried placing .tiff files in the input folder. I aslo tried changing the script to look for the file format I'm using .jpg.
var PictureFiles = firstFolder.getFiles(/\.(jpg|jpeg)$/i);
I have shots comprised of jpg image sequences. I'm processing the shots. When I process them, position and scale for a portion of the image is offset. I'm trying to use your script to perspective auto align the processed image to match the original image.
So I believe I need a script to:
1. Load original image into layer 1.
2. Load processed image into layer 2.
3. Designate the original image on layer 1 as the reference, so that the processed image on layer 2 is perpective transformed to match the original image on layer 1.
4. Auto-align layer 2 to layer 1.
5. Export the aligned layers, with layer 2 on top, to an uncompressed file (not .psd).
6. Repeat script on each matched pair until all pairs in the folders are procesed.
I also assume that in your script:
"Folder 1" = original files (contains the first set of matched pairs identically named as their match in folder 2).
"Folder 2" = processed files (contains the other set of matched pairs identically named as their match in folder 1).
"Output Folder" = photoshop aligned exported file.
Here is a link to two test files, in the folders I used to test the script:
FYI - The processed image is only the portion of the frame that has been position and scale offset by the processing. So the result I'm looking for is exactly what photoshop does when you manually auto-align the two uploaded images. I don't want the processed image to be auto-aligned to full frame, just aligned against the portion of the original image that came from.
Totally willing to pay for your time for a solution. We can DM or Discord, or something.
Thanks!
