Features and measurement parameters
Scientific Counter combines object detection with quantitative measurement. This makes the software useful not only for counting, but also for evaluating size, brightness, and shape distributions.
Image preprocessing
- Inversion for dark objects
- Evaluation of individual color channels or grayscale images
- Background correction for brightness gradients
- Mean filter for small disturbances
Object selection
- Threshold for bright object regions
- Minimum and maximum size
- Minimum and maximum brightness
- Minimum and maximum shape factor
- Removal of inclusions
Control
- Step-by-step test analysis
- Detail view with zoom
- Manual inclusion and exclusion of objects
- Marker colors for visual inspection
Direct object parameters
| Parameter | Benefit |
|---|---|
| Area and perimeter | Basic values for counts, size distributions, and many derived shape measures. |
| Minimum and maximum Feret diameter | Describe the smallest and largest projection of the object extent. |
| Inner and outer circle | Help evaluate spatial extent and shape. |
| Convex hull | Basis for evaluating indentations, cracks, and possible object overlaps. |
Derived shape parameters
Derived parameters include Feret ratio, radius ratio, shape factor, Wadell roundness ratio, degree of curvature, Horton compactness, Tickell ratio, Pentland projection, elongation ratio, convexity, deformation, and solidity.
Result export and documentation
- Overall result with object count, density, porosity, and statistical values.
- Detailed results for each detected object, if individual objects need further evaluation.
- Text files for spreadsheets and statistics programs.
- Report output with analyzed image, histogram, and result values.
- SHA-256 checksums for the image file, options, and result to support verification.
