Find Edges with ImageJ Programmatically

Question

I want to use find edges option of the ImageJ, have the edges-found array and save it to another file programatically.

ImagePlus ip1 = IJ.openIm         


        

Answer 1

ImageProcessor is an abstract class, that lets the derived classes provide the appropriate implementation. You need to declare ip as type ColorProcessor:

ColorProcessor ip = new ColorProcessor(ip1.getWidth(), ip1.getHeight()); 
ip.findEdges();

Answer 2

OK, I got the solution, the problem was that I didn't connect the ColorProcessor with the image.

ColorProcessor ip = new ColorProcessor(ImageIO.read(new File("my_image.jpg")));
ip.findEdges();
BufferedImage bimg = ip.getBufferedImage();
