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
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();
