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.
• v1.1
  • Added support for filter parameters that are manipulatable in the GUI.
  • Cleaned up and updated the README file.
• v1.1.1
  • Fixed bug: The GUI editors for the filter parameters now check to make sure that the inputted value for a parameter is within the parameter's minimum and maximum values.
• v1.2
  • Made plugin architecture easier to use.
    • To add a plugin to the GUI now, just add its .class file to the plugins folder.
    • This can be done automatically if you write your plugin inside the srcplugins folder and then build it using the make pluginsWithDist command.
  • Updated README file to explain the new way of adding plugins to the GUI.
• v1.2.1
  • Minor corrections make to the Makefile
  • Added color conversion routines (between ARGB and AHSB) to the Pixels utility class
  • Added several new filters
    • RGB Channel Filters
      1. RedChannelFilter
      2. GreenChannelFilter
      3. BlueChannelFilter
    • HSB Channel Filters
      1. HueChannelFilter
      2. SaturationChannelFilter
      3. BrightnessChannelFilter
    • BarrelHilighterFilter (experimental) - hilights areas of images where the difference (Red - Green) = Orange is large
• v1.2.2
  • Added BufferedImageFilter2, a new type of filter.
  • Added PixelBufferToBufferedImageFilter, a new type of filter.
• v1.2.3
  • Added FloatFilterParam, a new type of filter parameter.
  • Added DoubleFilterParam, a new type of filter parameter.
  • Added a Threshold parameter to BarrelHilighterFilter.
  • Added BarrelBlobFinder, an experimental new filter that locates and draws bounding boxes around barrels.

Future Versions (Planned)

• 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.

Feature Requests

• Ability to apply multiple filters (in a specific order) --Andy
  • Workaround:
    1. Load the original image.
    2. Select the first filter.
    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
