imagej

I am facing a challange in my field and I would need some advices. I have an image with tree rings. To see a photo I want to work with, you can check it from my dropbox: https://dl.dropboxusercontent.com/u/65873264/Sample.jpg I would like to write a macro/task... in which program will recognize each ring and mark it as ROI. I was trying to make this task using some plugins: Template Matching, Feature Finder and Visual grap. But those rings could be extremely variable. What I need is something like that: With Analyze particles function program recognize all vessels (objects) on a thresholded

I am new to ImageJ and I am seeking to add grain (as defined here: http://en.wikipedia.org/wiki/Film_grain ) to an image using the programmatic API of ImageJ. Is it possible? If so how? Where is the relevant documentation/Javadocs regarding adding grain to an image using ImageJ? I'd start in Process > Noise , described in ImageJ User Guide: §29.6 Noise . You'll have to decide if the existing implementations can be made to meet your requirements. Where I can find documentation on how to achieve this using the actual API instead of the UI . As discussed in ImageJ Macro Language , one easy way is

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.openImage("myimage.jpg"); ImageProcessor ip = new ColorProcessor(ip1.getWidth(), ip1.getHeight()); ip.findEdges(); However, the function findEdges is abstract and I can't have the edge-found image. EDIT: I wrote the following lines: ip.findEdges(); BufferedImage bimg = ip.getBufferedImage(); However, when I try to print out the RGB values of the BufferedImage, it only prints "-16777216" for each pixel RGB. OK, I got the solution, the problem was that I didn

When starting my Java application, I get exceptions when trying to save images. In Eclipse, however, everything works fine. The application is built using fatjar and the necessary libraries (jar_imageio.jar and ij.jar) have been selected for export as well. I tried using ImageIO and ImageJ: a.) ImageIO: ImageIO.write(image, "jpg", new File(f)); Exception in thread "main" sun.misc.ServiceConfigurationError: javax.imageio.spi.ImageWriterSpi: Provider com.sun.media.imageioimpl.plugins.jpeg.CLibJPEGImageWriterSpi could not be instantiated: java.lang.IllegalArgumentException: vendorName == null! at

I am having some trouble in ImageJ with one of its files. Basically set up a desktop pane that analyzes and opens images. But when the program opens the image it opens it as a separate JFrame. I would like to be an internal JFrame. So basically the image opens up in the desktop pane. I have tried a couple of things like creating a internal frame class and adding the win to the desktopPane but nothing seems to work it still opens it as a separate JFrame. I was wondering if anyone knows how to do this. This is my code (this function is just calling .show() to display the image, the code for the

I am using Python to design a software, and the image processing is one of the steps. I am using ImageJ to realize this. Since there is a Jython interpreter within ImageJ, which can be opened within ImageJ software, there must be a way to connect ImageJ to Python and call all the functions within Python. I wonder how I can do that to finish all the processing in Python rather than open the interpreter in ImageJ? There is this https://github.com/imagej/imagej.py module which provides an integration between Python and ImageJ. With it you can easily use ImageJ in Python. Here is a sample script:
