I have two questions -
1) Is there a way to analyse or extract metadata of images of type jpeg, png, gif, bmp? I need to be able to perform some quantitative analysis on the image metadata.
I am working on a security problem which aims at using exploratory methods to identify malicious images, and I figure that performing some kind of quantitative analysis on the image metadata would be the best way to do it. Is there any plugin/feature that will help me do this?
2) I have written a macro in ImageJ to run "Measurements" on a list of JPEG image files. I am running the code on a remote linux machine in headless mode using headless.jar.
I get the following excpetion -
> java.awt.HeadlessException: No X11 DISPLAY variable was set, but this
> program performed an operation which requires it.
> at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:159)
> at java.awt.Window.<init>(Window.java:433)
> at java.awt.Frame.<init>(Frame.java:403)
> at ij.plugin.frame.PlugInFrame.<init>(PlugInFrame.java:13)
How do I override this? Is there a way of preventing ImageJ from opening a graphics environment?
Thanks for the help in advance. :)
