Version 1.75.1 changelog

Image processing

Various nodes that generate statistics on labels

• Node “Merge 2D slices into hyperstack” (inverse operation of “Split into 2D slices”). Intended for more advanced filtering of hyperstack slices.
• Node “Merge small labels” (merges labels with a low number of pixels into a neighboring label index)
• Node “Key/Value Histogram 5D”
• Node “Key/Value threshold statistics 5D”
• Node “Key/Value statistics 5D (fast averages)”
• Node “Key/Value threshold statistics 5D (fast averages)”
• Convolve operators now have normalization parameter
• Convolve operators now support RGB images (same behavior as ImageJ)

Data processing

Node “Filter by annotation” (more compact version of “Split & filter by annotation” that applies the same operation)

Expressions

• New function STRING_FORMAT (C-style string formatting)
• New function NUM (Alternative to TO_NUMBER)
• Expressions that return numbers: valid numeric strings are automatically converted to numbers (before there was an exception if not a Number type is returned)
• Escaping of expressions did not work as expected (errors if sub-strings contained spaces)

User interface

• New “Memory” menu in the status bar that contains all memory-related operations (before was only a gear icon)
• “Reduce memory” moved into the “Memory” menu
• Number editor behaved erratically in non-english locales (now uses the advanced number parser capable of parsing NA and infinity)

Bugfixes and small improvements

Please refer to the commits in the JIPipe GitHub repository to find a list of all bugfixes and improvements.

• Various expression-based nodes now support custom expression variables: Filter labels by statistics, Filter ROI by statistics, Change ROI properties (Expression), Set ROI metadata by statistics (expression), Sort ROI list (expression)
• Numeric function expression now appropriately sets the default variable
• Crop 2D node: expression variables are now all annotated
• “Examples” panel now always shown
• Data processing: empty data batches are removed/ignored (only affects nodes with optional inputs)
• Various exceptions caused by the “Data batches” panel
• Image viewer: Movie/sequence export was not adhering to magnification level (cut-off images)
• Users were able to enable ROI/Mask for “Bright spots segmentation 2D”, “Hessian segmentation 2D” and “Internal gradient segmentation 2D”. Users are now advised to build a custom set of nodes (documentation was added)
