perClass Mira

Current version: 4.2 (13-mar-2023)

• new Camera and Images modes allow easy transition between live acquisition and working with saved scans
• support for perClass Stage

• includes user-defined commands for stage hardware buttons
• support for a quick setup of a camera (auto-exposure, focus and square pixels)
• Silios CMS using Silios SDK

• new Cross-validation tool

• Easily perform leave-one-out, rotation and randomization cross-validation for classification or regression
• Supports cross-validation over images or over replicas (multiple scans of one physical sample that need to be all either in training or in the test set)

• new tool to add manual object separation to existing object segmentation

• This allows one to pack more objects in one scan even if touching. Manual object separation does not extend to deployment.
• Object separation enables also fine control on areas used for regression analysis

• new sensor support

• full support for Headwall MV.C VNIR and NIR cameras
• partial support for legacy Headwall HyperspecIII cameras (currently VNIR and NIR supported, not SWIR)
• support for snapshot filereader
• experimental support for Agrowing sensors

• new perClass Camera API

• provides a unified interface for embedding data acquisition into custom applications

Current version: 4.1 (22-sep-2022)

• New docking system with user-defined perspectives over multiple screens
• New sensor support

• HAIP BlackIndustry
• Headwall MV.X using Pleora eBUS
• Silios CMS using Silios SDK

• Data acquisition

• New frame widget showing line scan frames and spatial/spectral profiles (live and off-line)
• New belt visualization of live data stream including object-level decisions
• Filereader plugin for line scans supporting multiple cubes and framerate setting

• New application server

• perClass Mira acquisition can be controlled via text commands over TCP/IP
• this allows quick construction of live demonstrators including custom actuator without low-level programming
• separate object detection channel allowing one to react on detections

• User-defined visualization color maps
• Improved alpha layer (two sliders, one for all classes, one for a specific class)

• Fixes

• Excel export of full spectral uses .xlsx file format by default allowing up to 16k columns
• adjustments of the confusion matrix to avoid unreadable text due to close foreground/background colors
• fixed auto-detection of ENVI cubes without extension
