ImageFilterDemo is a program that allows rapid prototyping of image filters in Java. This program was written by David Foster.

Program & Source Code

• v1.0
  • Original version
• v1.0.1
  • Added PixelBufferFilter2, a new type of filter.
  • Added contour extraction filters for the horizontal, vertical, and plus (horizontal+vertical) directions.
• v1.0.2
  • Addressed issue with loading certain images on Windows systems.
    • Specifically, java.awt.Toolkit.prepareImage(Image, int, int, ImageObserver) on Windows does not notify the specified ImageObserver when images are finished loading under certain conditions.
    • Credit goes to Andy for discovering this bug.
• v1.0.3
  • "Select..." button for selecting files now remembers the last file that was selected (even across different invocations of the program).
  • Added support for dragging & dropping files into the "file well".
• v1.0.4
  • Added ability to save filtered images to disk.

Future Versions (Planned)

• v1.1 - Coming soon!
  • Added support for filter parameters that are manipulatable in the GUI.
  • Made plugin architecture easier to use. To add a plugin now, just add its .class file to the plugins folder.
• v2.0
  • New input source: Image sequences
  • New input source: Movies (.mov, or other formats that QuickTime can handle)
  • Added support for temporal filters. These are filters that are designed for processing several images in sequence.

    3. Save the filtered image.
    4. Load the filtered image.
    5. Select the next filter.
    6. Repeat until no more filters.
• Ability to save config profiles for each filter. --Andy
  • ...to file, to preferences, or to both? --David
