Particle Analysis Report
Description
Returns the number of particles detected in a binary image and an array of reports containing the most commonly used particle measurements. Type : polymorphic.
Input parameters
Image Src : class, type accepted U8.
Connectivity 4/8 (8) : boolean, specifies the type of connectivity used by the algorithm for particle detection. The connectivity mode directly determines whether an adjacent pixel belongs to the same particle or a different particle.
-
- True : particle detection is performed in connectivity mode 8
- False : particle detection is performed in connectivity mode 4
Output parameters
Number Of Particles : integer, indicates the number of particles detected in the image.
Region Reports : array, returns a set of uncalibrated pixel measurements from the detected particles.
Area : float, is the area of the particle. Number of Holes : float, is the number of holes in the particle.
Bounding Rect : cluster, is the smallest rectangle with sides parallel to the x-axis and y-axis that completely encloses the particle. Center of Mass : cluster, is the point representing the average position of the total mass of the particle assuming every point in the particle has a constant density. Center of Mass may be located outside the particle if the particle is not convex. Orientation : float, is the angle of the line passing through the particle center of mass with the lowest moment of inertia. Dimensions : cluster, indicates the width and height of Bounding Rect.
