1.3.1

Fixed

  • Fixed issue where image scale factor in translation alignment was being used as minimum image overlap instead
  • Removed crash from FileNotFoundError exception. It does not exist in Python 2.7.
  • Support for histogram numpy images
  • Fixed very rare error where a subregion in translation alignment was a single pixel which broke statistics. These regions are now ignored
  • Force rectangle to use float64 numpy arrays. Fixed issue where integer arrays were passed and then used without conversion.
  • Fixed a bug where a non-existent center section was requested to be the center in the registration tree.

1.3.0

New

  • The original ir-refine-translate code from SCI has been replaced with a Python implementation. This appears to solve problems where tiles in mosaics were occasionally out of position
  • Richer API for Rectangles. Added functions to change the area but keep the same center, safe rounding to an integer that does not decrease the overall area,
  • Added a crude measure (Difference of overlapping regions) of mosaic quality
  • One can include titles in the ShowGrayscale function now

Fixed

  • Close pools more agressively. The extra threads multiprocessing pools spawn have a measurable performance cost, at least when running in low priority mode
  • Do not crash when a file is missing if we are checking a list of tiles and transforms for the most common scalar.
  • Adding stos transforms no longer removes masks from the .stos file.
  • .stos file object's mask FullPath functions no longer crash if passed None. Instead masks are properly cleared now.
  • .stos file can read mask paths correctly from .stos files, was reading the header line as a mask name before.
  • If all pixels are masked then do not try to calculate statistics for unmasked pixels.
  • Fixed mask generation in RandomNoiseMask
  • Fixed crash when MostCommonScalar function encounters a missing image file
  • AddStosTransforms was not passing masks along to the new .stos transform
  • We now raise a value error when a random noise mask does contain any unmasked pixels to generate statistics from.
  • Fixed output of unmapped pixels when warped image call is mapping a single image and not a list of images.
  • Fixed script generation on install. Scripts for individual operations such as assemble should appear now. More testing required here.
  • Fixes for the use of memory mapped files. These are still disabled in production.
  • Fix for crop image when the cropped image is entirely outside the boundaries of the input array.

Changed

  • Show grayscale layout and title improvements
  • ExtractRegion removed and replaced with faster, simpler CropImage function. Now raises DeprecationWarning.
  • Deleted unused functions
  • Rectangle object now always stores bounds internally as a numpy array
  • OnTransformChanged does not fire on a thread unless there are multiple listeners. Performance improvement
  • Numpy floating point issues not raise an exception instead of a warning message. Now using: numpy.seterr(all='raise')

1.2.4

Fixed

  • Support for translating tiles in a mosaic based on stage position
  • Bug fixes

1.2.3

New

  • Support JPEG2000 and memory mapped numpy arrays as image output formats
  • Use a generator to iterate through tiles pulled from a larger image.
  • Some significant memory footprint reductions for assemble and transformation functions

Fixed

  • Do not throw an exception when asking a .stos file for the full path to a mask that it doesn not have. Return None instead.

1.2.2

Minor optimization and function used in the new tile web server

New

  • Added a function to cut image into tiles
  • Added a resize image function
  • Reduced memory footprint of assemble somewhat.

1.2.1

New

  • Many optimizations to assembling images
  • Tests will be profiled if the PROFILE environment variable is set

1.2.0

New

  • Added bounding box to spatial
  • Python 3 support
  • Better documentation for assemble parameters.
  • Added bounding box structure to spatial module

Fixed

  • The output buffer in assemble is now the correct size. Previously a larger buffer was allocated and cropped.

1.1.7

New

  • RegistrationTree supports missing centers by finding the nearest section to the requested center

1.1.3

New

  • Add flag to StosBrute to allow execution on cluster
  • AssembleTiles method allows specifying a subregion to assemble
  • ShowGrayscale function displays multiple images on a 2D grid for a more optimal use of screen real estate
  • Added Spatial package which includes enums for standard indexing of nornir spatial arrays. For example iArea.width is the index to use to obtain the width from a size tuple

Changed

  • Bounds functions now follow the (MinY MinX MaxY MaxX) convention consistent with numpy image array indexing
  • Alignment record now uses the standard (Y,X) indexing of the other image_registration packages.
  • Removed many uses of ImageMagick identify to obtain image size and replaced with Pillow calls

Fixed

  • Image padding was making images larger than they had to be. This fix should increase registration speed

1.1.0

  • Initial release
