Annotation and Evaluation

Annotation and evaluation

Following features are allways implemented for mono-image annotation and evaluation:

  • You may zoom, rotate and drag the image without flicker (Open GL)
  • 3D mice (SpacePilot) are supported.
  • Associate detailed description.
  • Annotate details within the image using Markers
  • Further geometrical objects (rectangles, ellipses, squares, circles, lines, contours) highlight structures within the image
  • Export function for publications
  • Measure angles.

Measuring is automatically possible, in case a micrometer factor is given for the optics combination used with your shoot.

  • Measure Distances (straight line, irregular line)
  • Borders (elliptical, rectangular, irregular shaped)
  • Area (elliptical, rectangular, irregular shaped)
  • Volume (Spheroid, Quboid)
  • Shallow volume (Cylindric, spheroidic)
  • All measured items may be edited and configured

Transparency - an important feature for annotations

With area or volume measurements E.L.M.I. uses transparency to highlight the region covered.

The transparency may be tuned infinitely variable.

An example for transparent annotation:

Cysts of Toxoplasma gondii in a brain.

This image comparison shows, how annotation benefits from transparent annotation.
The volume of the estimated spheroid does not cover important image informations (sporozoids within the cystis) too much.

On the other hand, the covered section used for estimating the associated volume is clearly visible .

Global annotation

Example for global and local annotation. The algorithm beyond generates resultfiles, which are managed by the relational database engine. No changes are made to your original image data at any time.

The design of the annotation algorithm provide maximum flexibility for exportation. In future releases this topic will be extended.
