Table 1 Parameters computed for each particle segment and their descriptions
Parameter | Description |
|---|---|
Area | The number of pixels in a region |
Centroid | The center of pixel mass |
Solidity | The ratio of shared pixels between the segment and its convex hull |
Perimeter | The length of the resulting active contour around the studied particle. |
Major axis length | Major axis length of an ellipse with the same second central moment as the segmented object |
Minor axis length | Major axis length of an ellipse with the same second central moment as the segmented object |
Orientation | Major axis orientation of an ellipse with the same second central moment as the segmented object |
Equivalent diameter | Diameter of a circle that has the same area as the particle |
Circularity | Ratio of shared pixels between the segment and its convex hull |
Aspect ratio | The ratio of major and minor axis (see above) |
