MIPAV change list 1.xx

1.60 (01/13/2006)

• The functionality provided by the Dual Tri-Planar view has been collapsed into the Tri-Planar view (Image -> Views -> Triplanar). When a second image is loaded, the Tri-Planar image display changes to show both images, shown as it was in the Dual Tri-Planar view. Region growing and bounding cube operations are still being refactored and do not function correctly in this release. Position information is now shown in a separate window accessible from the menu item (Options -> Show volume coordinates and talariach controls) in the Tri-Planar frame.
• Added the ability to read and save surfaces in a new XML format.
• Scripting support has been added the the Fill Objects algorithm (Algorithms -> Morphological -> Fill holes)

• Image subsampling (Utilities -> Subsample) now supports transforming VOIs within the image.
• Show costs (Algorithms -> Registration -> Display pixel similarity cost functions) now supports 2D images.
• Fixed the VOI perimeter statistic in the VOI property dialog.
• A new image padding utility has been added (Utilities -> Pad with slices)
• A bug in adjusting the paint opacity has been fixed.
• Fixed an issue with 0 to 1 LUT adjustment for image B.
• Point VOIs can now be shown as one of four different images: normal, normal with the center pixel removed, an X, and an X with the center pixel removed. Which one is used can be changed through the MIPAV Options dialog (Help -> Program options).
• Selected VOI points can now be adjusted through use of the arrow keys.
• 2.5D processing is now supported in the Skeletonize algorithm (Algorithms -> Morphological -> Skeletonize).
• Handling of multi-file images when loading a second image into a frame is now consistent with the process for reading in the first image.

  • Algorithms -> Transform to power of 2
  • Utilities -> Add image margins
  • Utilities -> Insert slice
  • Utilities -> Match images
  • Utilities -> Noise

1.59 (12/12/2005)

• Fixed a problem when running the software when the MIPAV configuration directory does not already exist ($HOME/mipav), which would prevent MIPAV from running unless the directory was manually created. If not found, it is now created automatically.
• The TriPlanar view (Image -> Views -> Triplanar) has been greatly improved and most functions should now function correctly. Coordinate display, mouse wheel navigation, painting, and VOI operations for all image orientations now work.
• When the TriPlanar view is open, clicking with the middle/scroll button in the original image will center the TriPlanar view at the clicked point.
• If MIPAV is run without a GUI (i.e., with the -hide option), encountering an error will cause the software to exit with an abnormal value (1).
• Snap-to-pixel behavior while painting has been finished and is no longer an option that can enabled or disabled.
• Both active and non-active scripts generated by MIPAV can now be used interchangeably.
• The Crop utility (Utilities -> Crop) now always creates a new image.
• Opening the Volume Renderer (Image -> Views -> Volume Renderers) by clicking the padding button when no padding is necessary no longer causes an exception.
• Miscellaneous bug fixes and improvements have been made in the following areas:
  • Algorithms -> Fuzzy C-means -> Multispectral
  • Algorithms -> Histogram equalization -> Neighborhood adaptive
  • Algorithms -> Histogram equalization -> Regional adaptive
  • Algorithms -> Image calculator
  • Algorithms -> Extract brain -> Extract brain surface (BSE)

  • File -> DICOM browser
  • Writing of some TIFF image files.

1.58 (11/18/2005)

• Multifile and single file images are now opened from the same menu item (File -> Open new image(A)) and how an image is opened is controlled by a checkbox in the File Selection dialog.
• Fixed a number of issues when using MIPAV to receive DICOM images over a network (File -> DICOM receiver on/off).
• The drawing and display of images has been greatly improved. It is now faster, with reduced flicker when moving VOIs and the mouse cursor. The interpolated mode of displaying images has also been updated, allowing for either image A or image B or both to be interpolated independently and making it so that paint on an interpolated image does not appear interpolated (blurry). Work on updating the TriPlanar view (Image -> Views -> Triplanar) to make use of these improvements is continuing and should be available in the next version of MIPAV. Users who need to paint or perform other operations in the TriPlanar view besides simply viewing images should not upgrade at this time.
• An option in the MIPAV Options dialog (Help -> Program options) now allows for the user to choose whether the paint cursor should exhibit snap-to-pixel behavior.

  • Algorithms -> Edge detection -> Zero X laplacian
  • Algorithms -> FFT
  • Algorithms -> Filters (frequency)
  • Algorithms -> Filters (spatial) -> Mode
  • Algorithms -> Filters (spatial) -> Nonmaximum suppression
  • Algorithms -> Filters (spatial) -> Unsharp mask
  • Algorithms -> Fuzzy C-means -> Multispectral
  • Algorithms -> Shading correction -> Inhomogeneity N3 correction
• Running scripts on multiple images from the command line has been fixed.
• Work is continuing on updating and improving Volume Renderer (Image -> Views -> Volume renderers).
• The Volume Renderer now has been tested with the latest versions of Java 1.4 and 5.0 (1.5) on Mac OS X 10.4.

1.57 (10/28/2005)

• The Load Image dialog (File -> Load -> Image(B) from frame) now has the "Match orientations of two images." and "Use image origin information to align images." default to being selected.
• The Save As dialog (File -> Save image as) now defaults to the image's filename.
• Fixed the handling of the image resolution when saving an XML file from a DICOM image.
• Two 2D images can now be matched (Utilities -> Match images).
• Multi-file images can now be opened from either the Open Image dialog (File -> Open new image(A)) or the Open Multi-file dialog (File -> Open multi-file(A)) through the use of a checkbox.
• Reduced the amount of flicker of progress bars and defaulted them to appearing in the center of the screen.

To open the full multi-file image set, use the File -> Open multi-file(A) menu item. Multi-file image sets show up in the recently used images list of the File menu with (M) appended to their file name.
• The DICOM reader has been fixed so that images with singular transformation matrices can still be read.
• The Rotation utility now correctly sets the new image's orientation.

1.54 (09/26/2005)

• Improved the BET Brain Extractor (Algorithms -> Extract brain -> Extract brain surface (BET)) segmentation slightly.
• Constructors for FileIO and ViewJFrameImage which take ViewUserInterface objects have been deprecated. All other constructors which take ViewUserInterface will be deprecated over the course of the next month or so. Eventually, these constructors will be removed completely. ViewUserInterface has been changed to be a singleton class, meaning that there is only one occurance of it anywhere within MIPAV. The practical upshot of this is that plugin writers will have to adjust to use the new constructors as they are added, and use the function ViewUserInterface.getReference() if they need to use the user interface for something.
