arivis Vision4D 4.1

Summary of changes in arivis Vision4D 4.1, released 27 March 2023

arivis AI Toolkit

new: Optional module arivis AI toolkit:
new: Deep Learning Trainer panel to setup and train a DL model
new: use the Draw Tool to draw segments to annotate regions for classes
new: utilizing of sparse annotations to overcome the need to draw on every pixel
new: drawn objects are sorted by class order - pixels are assigned to the topmost one (no need to cut out overlaps)
new: add and reuse existing segments for class definition
new: automatic clustering based on annotated backgound possible
new: run and monitor the DL training process right from Vision4D
new: directly open the trained DL model in the Analysis Pipeline for inference
new: export the trained DL model as ONNX
new: additional installer package to setup a whole DL Python environment

new: 'Neuron Tracer' (from the Segmentation category) has been renamed to 'Neurite Tracer'
new: 'Neuron Tracer (from Cell Body)' has been renamed to 'Neuron Tracer'
new: Neuron Tracer preview shows all parts in the same color
new: Neuron Tracer preview shows the filtered parts slighly dimmed (instead of hiding them completely)
improved: parameter labels in the Neuron Tracer are more precise
improved: default threshold value and threshold warnings in the Neuron Tracer
improved: tooltips in the Neuron Tracer
fix: if the tracking operation had a lot of results, it could happen that the last tracks were not displayed
fix: prevent the creation of (almost) empty traces in the Neuron Tracer
fix: ensure that a preview progress label is always displayed immediately

new: display of starting points can be turned off for traces
improved: optimized cone generation for traces in 4D Viewer
improved: fallback to line based visualization if cones for traces would exceed memory
improved: remember last used Z-Projection value for trace visualization in 2D
fix: minor problem with RGB Projection in 4D Viewer

new: Wellplate Editor to manually assign imagesets to wells or fields of a well
new: semi-automatic assign imagesets to well or field positions based on the name of the imageset (in the Wellplate Editor)
new: additional import scenario to import wells as imagesets and open the Wellplate Editor afterwards (for manual assignemnt)
fix: some LaVision data could not be imported correctly for TileSorter
fix: problems with some CZI if imported for TileSorter

new: Predictive Analytics service as optional install
new: gRPC service connector
new: ZenBridge is able to work with gRPC service connector (optionally)
improved: included Sentinel driver and HASP Lib have been upgraded to version 8.5
fix: sort order in field selector of Navigator (for wellplate data)
fix: rare crash in the Transform Surface dialog
additional minor fixes and improvements
