Macro to run Laplacian on stacks

peppetin
Hello!

I am using a FeatureJ ( plugin ) tool in order to perform a Laplacian on my images but , unfortunately ,
this Laplacian can't work with image sequence ( stacks ) .
Can you help me to write a macro with these steps :

1. Open images singularly from a folder :
2. Apply "Laplacian " to each image ;
3. Save the treated images in another folder .

I hope you can give me a bit of support .

Thank you in advance to all the community that is so great .

You can use Process > Batch > Macro...

Put the run(FeatureJ, options) in the text box and you should be good to go. You can use macro recorder to generate this line.

Hi,
The problem is that featureJ is producing a new image with name
<originalimage>-Laplacian. And you need to account for that.
I' ve  just the macro you need. As a basis I used an old batch processing
macro created by porifera.net. It will ask about source folder, destination
folder and filter size and will process all images in the source folder
with the preselected filter size of the Lap[lacian of Gaussian  and save
them to the destination.
Best regards,
Stoyan

//Macro START

//Batch Processor

 function convert(format) {
     requires("1.34m");

// *** General Settings ***


// Close log window if open
       if (isOpen("Log")) {
        selectWindow("Log");

// ### End Input specific functions ###


// Choose directories
     dir1 = getDirectory("Choose source image directory ");
     dir2 = getDirectory("Choose FILTERED IMAGE destination directory ");
     list = getFileList(dir1);
    b = getNumber("Gaussian blur radius (in scaled units):", 2);

// Protocol start
       print("ImageJ macro 'Batch_Processor' by porifera.net \n \n");
       print("initial file source directory: ",dir1, "\n");

            processFile(path);
               }
               }
       }

 function processFile(path) {
      if (endsWith(path, "")) {
          open(path);

// *** Insertion specific operations ***

run("FeatureJ Laplacian", "compute smoothing=&b");
selectImage(initimage);
close();
selectImage(initimage+" Laplacian");
rename(initimage);

// *** End Insertion specific operations ***

// Save and close images

       // Safe and close FILTERED IMAGE
         selectWindow(initimage);
         saveAs(format, dir2+"Laplacian_of_Gaussian_r"+b+"_"+list[i]);  //
Safe with a prefix indicating filter radius
         close();


//Print progress report
print("processed file ", list[i]);

     }
 }

//Final message progress report
print("successfully processed ", list.length, " files");
showMessage("Batch processing finished");

 }


macro "Abort" {
