Imagin

Interactive Viewer/Analyzer for streamed images or files based on python, pyqtgraph and scipy.

Features:

• Input source:
  • File system,
  • HTTP link to image,
  • EPICS PV,
  • Local USB cameras (requires openCV).
• Default image format is PNG, other formats supported as well.
• 16+ bit/channel images supported.
• Image orientation and arbitrary rotation.
• Interactive zooming, panning, rotation.
• Contrast/Coloration control.
• Region Of Interest (ROI) for image analysis.
• ROI partitioning.
• ROI projection plots.
• Isocurves. The isocurve level defines the threshold for object finding.
• Fast and robust characterization of multiple objects using fitted ellipsoids.
• Gaussian (1D and 2D) fit for improved precision.
• Effective de-speckling.
• Automatic elimination of background using prominence filter (de-base).
• Background subtraction using a reference image.
• Interactive calibration of pixels to millimeters.
• Reference Images: save/retrieve image to/from a reference slots.
• Easy extentable using with user-suplied add-ons.
• Fast browsing/cleanup of image directories.
• Interactive python console with access to image data, graphics objects and shell.
